Connecting the TB6548F/FG (or TB6537P/PG/F/FG) to the TA84006F/FG allows electric motors to be controlled

by PWM.

Note 4: In Prohibit Mode, the output power transistor goes into vertical ON mode and through current may damage

the circuit. Do not use the TA84006F/FG in this mode.
This mode is not actuated when the TA84006F/FG is connected to the TB6548F/FG or TB6537P/PG/F/FG,
but can be triggered by input noise during standalone testing.

<Schematic>

<Lower PWM>

Connecting the TA84006F/FG to the TB6537P/PG/F/FG controls the lower PWM.
At chopping ON, the diagonally output power transistors are ON.
At chopping OFF, the lower transistor is OFF, regenerating the motor current via the upper diode

(incorporating the Pch-MOS).

Equivalent Circuit

<Overcurrent detector (RF, VISD, ISD) >

Input to the VISD1 pin the voltage generated at the overcurrent detection resistor RF connected to the
RF pin.

At chopping ON, voltage spikes at the RF pin as a result of the Pch-MOS output capacitance. To cancel
the spike, externally connect a capacitor to the VISD2 pin. (10 k

resistor built-in)

If the VISD2 pin voltage exceeds the internal reference voltage (VRF

= 0.5 V), the overcurrent detection

output ISD pin goes Low.
Inputting the inversion of the ISD pin output to the TB6537P/PG/F/FG or TB6548F/FG OC pin limits the
PWM ON time and the current at the ISD output rising edge.

<Pin voltage detector (COMP) >

The pin voltage detector outputs the result of OR-ing the output pin voltages and the virtual mid-point N
voltage to determine the majority.
(If at least two phases of the three-phase output are greater than the mid-point potential, the detector
outputs "Low". Conversely, if at least two phases are smaller than the mid-point potential, the circuit
outputs "High".)

With the virtual mid-point potential VN used as the reference for the pin voltage detection circuit
considered as half the voltage applied to the motor, then
VN

<Example of 24 V support>

Incorporate a Zener diode and make the external connections shown in the diagram below. Design the
device so that the voltage applied to the VM is clamped at 22 V below the maximum operating power
supply voltage.

A capacitor is needed to control the effect of the counter-electromotive force.
Verification is particularly necessary when the motor current is large at startup or at shutdown (output
OFF).

pin fluctuation width

20.9 V to 23.1 V
Due to the temperature characteristics (3.5

× 3 mV/°C),

the following applies at an ambient temperature of 85°C:
V

(max)

= 23.1 + (85 - 25) × 3.5 × 3 mV

= 23.73 V

By taking the measures shown in the diagram on the right to bring
the voltage down to 22 V, the following becomes the case:
V

= 23.73 - (0.7 - 2 mV × (85 - 25) ) × 3

Notes on Contents

1. Block Diagrams

Some functional blocks, circuits, or constants may be omitted or simplified in the block diagram for

explanatory purposes.

2. Equivalent Circuits

The equivalent circuit diagrams may be simplified or some parts of them may be omitted for explanatory

purposes.

3. Timing Charts

Timing charts may be simplified for explanatory purposes.

4. Maximum Ratings

The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must not

be exceeded during operation, even for an instant.

If any of these ratings are exceeded during operation, the device electrical characteristics of the device may be

irreparably altered and the reliability and lifetime of the device can no longer be guaranteed.

Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in

other equipment. Applications using the device should be designed so that no maximum rating will ever be
exceeded under any operating conditions.

Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set

forth in this document.

5. Application Circuits

The application circuits shown in this document are provided for reference purposes only. Thorough evaluation

is required in the mass production design phase.

In furnishing these examples of application circuits, Toshiba does not grant the use of any industrial property

rights.

6. Test Circuits

Components in test circuits are used only to obtain and confirm device characteristics. These components and

circuits are not guaranteed to prevent malfunction or failure in application equipment.

Handling of the IC

Ensure that the product is installed correctly to prevent breakdown, damage and/or degradation in the product

or equipment.

Overcurrent Protection and Heat Protection Circuits

These protection functions are intended only as a temporary means of preventing output short circuits or other

abnormal conditions and are not guaranteed to prevent damage to the IC.

If the guaranteed operating ranges of this product are exceeded, these protection features may not operate and

some output short circuits may result in the IC being damaged.

The overcurrent protection feature is intended to protect the IC from temporary short circuits only. Short

circuits persisting over longer periods may cause excessive stress and damage the IC. Systems should be
configured so that any overcurrent condition will be eliminated as soon as possible.

Counter-electromotive Force

When the motor reverses or stops, the effect of counter-electromotive force may cause the current to flow to

the power source.

If the power supply is not equipped with sink capability, the power and output pins may exceed the maximum

rating.

The counter-electromotive force of the motor will vary depending on the conditions of use and the features of

the motor. Therefore make sure there will be no damage to or operational problem in the IC, and no damage to
or operational errors in peripheral circuits caused by counter-electromotive force.
