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. The Si9988 is available in both standard and lead (Pb)-free, 8-pin TSSOP packages, specified to operate over a voltage range of 3.8 V to 13.2 V, and the industrial temperature range of −40 to 85_C (D suffix).
