DESCRIPTION
The Si9986 is an integrated, buffered H-bridge with TTL
compatible inputs and the capability of delivering a continuous
1.0 A @ V
DD
= 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 to 70_C (C suffix) and the industrial temperature
range of -40 to 85_C (D suffix).
