DESCRIPTION

The Si9976 is an integrated driver for an n-channel MOSFET

half-bridge. Schmitt trigger inputs provide logic signal

compatibility and hysteresis for increased noise immunity. An

internal low-voltage regulator allows the device to be powered

directly from a system supply of 20 to 40 volts. Both half-bridge

n-channel gates are driven directly with low-impedance

outputs. Addition of one external capacitor allows an internal

circuit to level shift both the power supply and logic signal for

the half-bridge high-side n-channel gate drive. An internal

charge pump replaces leakage current lost in the high-side

driver circuit to provide “static” (dc) operation in any output

condition. Protection features include an undervoltage

lockout, cross-conduction prevention logic, and a short circuit

monitor.

The Si9976 is available in both standard and lead (Pb)-free,

14-pin SOIC (surface mount) packages, specified to operate

over the industrial (?40 to 85C) temperature range.
