SI9988 Overview
The Si9988 is an integrated, buffered H-bridge with TTL patible 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 simultaneously. Both outputs may be forced low (for motor braking) by pulling EN to logic high.
