FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
H-BRIDGE OUTPUT 1, 2 (OUT1 AND OUT2)
These pins are the outputs of the H-Bridge with integrated
output FET body diodes. The bridge output is controlled using
the IN1, IN2, D1, and D2 inputs. The outputs have active
current limiting above 6.5 A. The outputs also have thermal
shutdown (tri-state latch-OFF) with hysteresis as well as
short circuit latch-OFF protection.
A disable timer (time t _b) incorporated to detect currents
that are higher than active current limit is activated at each
output activation to facilitate detecting hard output short
conditions (see Figure 9, page 9).
CHARGE PUMP CAPACITOR (CCP)
Charge pump output pin. A filter capacitor (up to 33 nF)
can be connected from the C_CP pin and PGND. The device
can operate without the external capacitor, although the C_CP
capacitor helps to reduce noise and allows the device to
perform at maximum speed, timing, and PWM frequency.
