Selection guide

ROHM's BD52XXG/FVE and BD53XXG/FVE are series of high-accuracy, low-power VOLTAGE DETECTOR ICs

with a CMOS process. These series can set delay time by external capacitor. For flexible choice according to the

application, BD52XXG/FVE series with N channel open drain output and BD53XXG/FVE series with CMOS output

are available in 38 voltage types which detection voltage is from 2.3V to 6.0V in steps of 0.1V in different packages,

totaling 152 models.

To prevent the functional deterioration or thermal damage of semiconductor devices and ensure their service life

and reliability, they must be designed and reviewed in such a way that the absolute maximum rating can not be

exceeded in any cases or even at any moment.

Two output types can be used. One is BD52XXG/FVE (Left) of open drain output type, and the other is

BD53XXG/FVE (Right) of CMOS output type.

· Operating temperature range

The circuit function is guaranteed within the temperature range. However, the operating characteristics are

different from that of Ta=25°C. If they are any questions about the extent of guarantee of circuit functions

in this operating temperature range, please ask for more technical information.

· Output voltage

OUT

pin voltage should not exceed the indicated value. For Nch open drain output type, V

applied

voltage and V

OUT

pin H output voltage can be used independently. Both of them should not exceed the

each indicated value.

· Power supply voltage

This voltage is the applied voltage between V

and GND. The applied voltage should not exceed

the indicated value.

· Storage temperature range

This IC can be stored up to this temperature range without deterioration of characteristics. However, an

abrupt thermal shock of extreme temperature fluctuations may cause the deterioration of characteristics.

Operating explanation

·When V

is equal to or more than the release voltage (V

DET

), CT pin voltage becomes V

(External capacitor is in charging mode.) and output V

OUT

is in "H" mode. (Nch output transistor Q1 is OFF,

Pch output transistor Q2 is ON.) When V

is gradually decreased, Q3 connected to CT pin in the detection

voltage (V

DET

) switches OFF to ON, external capacitor is discharged, and CT pin voltage becomes

decreased. When the CT pin voltage is lower than the threshold voltage of next inverter, output (V

OUT

) turns

"L". (Nch output transistor Q1 is ON, Pch output transistor Q2 is OFF.)

· When V

is equal to or lower than the detection voltage (V

DET

), CT pin voltage is L voltage (External

capacitor is in discharging mode and Q3 is ON), output V

OUT

is in "L" mode. When V

is gradually

increased, Q3 is OFF in the release voltage (V

DET

) and CT pin external capacitor becomes to be

charged through resistor R1 in the IC. When the CT pin voltage is more than the threshold voltage of next

inverter, output (V

OUT

) goes from "L" to "H". (Nch output transistor Q1 is OFF, Pch output transistor Q2 is

ON.) Delay time is the time when output V

OUT

goes from "L" to "H" after the V

is more than the release

voltage. (V

DET

) Delay time can be set freely by the CT pin external capacitor. (Usage is shown at P10)

Ex.) For both open drain type (Fig.7) and CMOS output type (Fig.8), detection voltage and release voltage are

threshold voltage. When voltage applied to V

pin reaches each threshold voltage, V

OUT

pin voltage goes

"H" "L" or "L" "H'. BD52XXG/FVE and BD53XXG/FVE incorporate delay time circuit that can set delay time

by the external capacitor when output goes"L" "H". BD52XXG/FVE series are open drain types and pull-up

resistor must be connected to V

, or other power supply. (In this case, output (V

OUT

) H voltage is V

, or

other power supply voltage.)

Ex.) The relation between input voltage V

and output voltage V

OUT

when V

is increased and decreased

is shown below. (Circuit is shown in Fig7, Fig.8)

· SWEEP DOWN for V

· SWEEP UP for V

·Some hysteresis is given such a way that the release voltage is the detection voltageX(1.05 Typ.).

· The output becomes inconsistent if the V

is equal to or lower than the operating limit voltage.

Timing waveform

If the V

is equal to or lower than the operating limit

voltage (V

If the V

goes below the detection voltage (V

power-down or instantaneous power failure, V

. See Fig.16 for the reference waveform.

The potential difference between the detection voltage and

the release voltage is called hysteresis (V

The products are designed so as to prevent power supply

fluctuation within this hysteresis from causing fluctuation in
