DESCRIPTION
The Si9988 is an integrated, buffered H-bridge with TTL
compatible inputs and the capability of delivering a co ntinuous
0.65 A @ VDD = 5 V (room tem per at ur e) at s wi t ching rates up to
200 kHz. Internal logic prevents the upper and lower outputs of
either half-bridge from being turned on simultaneously. Both
outputs ma y b e forc ed l ow (for moto r braking ) by pu lling E N
logic high.

The Si9988 is available in an 8-Pin TSSOP package, 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).
