The TPIC0108B is a PWM control intelligent H-bridge designed specifically for dc motor applications. The
device provides forward, reverse, and brake modes of operation. A logic supply voltage of 5 V is internally
derived from VCC.
The TPIC0108B has an extremely low rDS(on), 280 mtypical, to minimize system power dissipation. The
control inputs (IN1 and IN2) greatly simplify the microcontroller overhead requirement. The device has a low
quiescent supply current of 20 µA to suit a wide range of automotive and industrial battery-operated
applications.
The TPIC0108B provides protection against over-voltage, over-current, over-temperature, and cross
conduction faults. Fault diagnostics can be obtained by monitoring the STATUS1 and STATUS2 terminals and
the two input control lines. STATUS1 is an open-drain output suitable for wired-or connection. STATUS2 is a
push-pull output that provides a latched status output. Under-voltage protection ensures that the outputs, OUT1
and OUT2, will be disabled when VCC is less than the under-voltage detection voltage V(UVCC).
The TPIC0108B is designed using TI’s LinBiCMOSprocess. LinBiCMOS allows the integration of low power
CMOS structures, precision bipolar cells, and low impedance DMOS transistors.
The TPIC0108B is offered in a 20-pin thermally enhanced small-outline package (DWP) and is characterized
for operation over the operating case temperature of −40°C to 125°C.
