DESCRIPTION

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

compatible inputs and the capability of delivering a continuous

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 to 70_C (C suffix) and the industrial temperature

range of −40 to 85_C (D suffix).
