Buffered H-Bridge Driver with Integrate MOSFET

DESCRIPTION

The Si9986 is an integrated, buffered H-bridge with TTL

compatible inputs and the capability of delivering a

continuous 1 A at VDD = 12 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. Unique input codes allow both

outputs to be forced low (for braking) or forced to a high

impedance level.

The Si9986 is available in both standard and lead (Pb)-free,

8-pin SOIC packages, specified to operate over a voltage

range of 3.8 V to 13.2 V, and the commercial temperature

range of 0 °C to 70 °C (C suffix) and the industrial

temperature range of - 40 °C to 85 °C (D suffix).
