The TPIC0107B 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 V
CC
.
The TPIC0107B has an extremely low r
DS(on)
, 280 m鈩?typical, to minimize system power dissipation. The
direction control (DIR) and PWM control (PWM) inputs greatly simplify the microcontroller overhead
requirement. The PWM input can be driven from a dedicated PWM port while the DIR input is driven as a simple
low speed toggle.
The TPIC0107B 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 V
CC
is less than the under-voltage detection voltage V
(UVCC)
.
The TPIC0107B is designed using TI鈥檚 LinBiCMOS鈩?process. LinBiCMOS allows the integration of low power
CMOS structures, precision bipolar cells, and low impedance DMOS transistors.
The TPIC0107B is offered in a 20-pin thermally enhanced small-outline package (DWP) and is characterized
for operation over the operating case temperature of 鈥?0擄C to 125擄C.
