DESCRIPTION
The Si9987 is an integrated, buffered H-bridge with TTL
compatible inputs and the capability of delivering a continuous
1.0 A @ VDD = 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).
