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).
