N-Channel Half-Bridge Driver
DESCRIPTION
The Si9976DY 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 V.
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 Si9976DY is available in the
14-pin SOIC (surface mount) package, specified to operate
over the industrial (-40 to 85
°
C) temperature range.
