DESCRIPTION
The Si9988 is an integrated, buffered H-bridge with TTL
compatible inputs and the capability of delivering a continuous
0.65 A @ 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 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).
