SEMICONDUCTOR TECHNICAL DATA
Full Bridge Pre-Driver
The MC33253 is a full bridge driver including integrated charge pump, two independent high and low side driver channels.
The high and low side drivers include a cross conduction suppression circuit, which, if enabled, prevents the external power FETs from being on at the same time.
The drive outputs are capable to source and sink 1 A pulse peak current.
The low side channel is referenced to ground, the high side channel is floating above ground.
A linear
regulator provides a maximum of 15.
5V to supply the low side gate driver stages...
