Si9988
Vishay Siliconix
Buffered H-Bridge Driver with Integrate MOSFET
DESCRIPTION
FEATURES
The Si9988 is an integrated, buffered H-bridge with TTL
compatible inputs and the capability of delivering a
continuous 0.65 A at VDD = 5 V (room temperature) at
switching rates up to 200 kHz. Internal logic prevents the
upper and lower outputs of either half-bridge from being
turned on simultaneously. Both outputs may be forced low
(for motor braking) by pulling EN to logic high.

•
The Si9988 is available in both standard and lead (Pb)-free,
8-pin TSSOP packages, specified to operate over a voltage
range of 3.8 V to 13.2 V, and the industrial temperature
range of - 40 °C to 85 °C (D suffix).
