Freescale Semiconductor, Inc. Order Number: MC33253/D Rev 3, 03/2001 Advance Information MC33253 55 VOLTS 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. The high side driver stages are supplied with a 10V charge pump voltage.
