The Si9986 is an integrated, buffered H-bridge with TTL
compatible inputs and the capability of delivering a
continuous 1 A at 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 °C to 70 °C (C suffix) and the industrial
temperature range of - 40 °C to 85 °C (D suffix).

Notes:
a. Device mounted with all leads soldered or welded to PC board.
b. Derate 10 mW/°C above 25 °C.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
