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).
