SI9988 Datasheet (Vishay Siliconix)

SI9988, Buffered H-Bridge

The Si9988 is an integrated, buffered H-bridge with TTL compatible inputs and the capability of delivering a continuous 0.65 A @ VDD = 5 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 simultaneousl
