DESCRIPTION

The Si9987 is an integrated, buffered H-bridge with TTL

compatible inputs and the capability of delivering a continuous

1.0 A @ V_DD= 5.0 V (room temperature) at switching rates up

to 500 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 Si9987 is available in an 8-Pin SOIC package, 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 −40

to 85_C (D suffix). The Si9987 is available in lead free.
