DESCRIPTION
The Si9988 is an integrated, buffered H-bridge with TTL
compatible inputs and the capability of delivering a continuous
0.65 A @ V DD = 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 to 85 _ C (D suffix).
