DESCRIPTION
The
PD168102 is a monolithic 6-channel H bridge driver IC consisting of a CMOS controller and a MOS output
stage. Because it uses a MOS process, this driver IC consumes less current and loses less voltage at the output
stage than conventional driver ICs that use bipolar transistors. In addition, the
PD168102 employs P-channel
MOSFETs in its output stage, eliminating the need for an on-chip the charge pump circuit. Therefore, the current
consumption during circuit operation can be significantly reduced.
Of the six output channels, four channels are voltage drive type and two channels are current drive type (voltage
drive is also possible). The current drive method of the
PD168102 is the output chopping method, which realizes
lower power consumption drive than the conventional high-power-dissipation linear drive method.
The
PD168102 is housed in a 48-pin WQFN to decrease the mounting area and height. The PD168102 can
simultaneously drive two stepper motors and two DC motors and is ideal for the motor driver of digital still cameras.

Constant current
chopping
H: High level, L: Low level, Z: High impedance
Constant current chopping is possible for channels 5 and 6.
When VIsel is set to high level, if the voltage becomes higher than the reference voltage (external input) and the
current becomes higher than the current set by the feedback resistor, the output can be forcibly chopped.
When VIsel is set to low level, channels 5 and 6 function in the same way as channels 1 to 4.
Standby function
The
PD168102 realizes a standby function by combining the input signals.
By setting all the control input signals of channels 1 to 6 to low level, a standby mode in which the current
consumption of the internal circuit is suppressed is entered. Note that the output status is high impedance
(output open).
BRKsel pin function
By using the logic of BRKsel, whether the function that prevents the motor power supply rising in the Hi-Z output
status (input L, L) is enabled or disabled can be selected. Refer to the truth table below.
BRKsel Truth Table
BRKsel
Function
L
Hi-Z status
H
Regenerates output current using an internal channel. An internal timer is incorporated, through which the
regeneration period is set for approx. 1 ms, and then the Hi-Z status is entered.
