DESCRIPTION
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).
