INTRODUCTION
   The L6234 is a DMOSs triple half-bridge driver with input supply voltage up 52V and output current of 5A. It can be used in a very wide range of applications.
   It has been realized in Multipower BCD60II technology which allows the combination of isolated DMOS transistors with CMOS and Bipolar circuits on the same chip. It is available in Power DIP 20 (16+2+2) and in Power SO 20 packages.

DEVICE DESCRIPTION
   The device is composed of three channels. Each channel is composed of a half bridge with two power DMOS switches ( typ. Rdson of 300mW @ 25°C) and intrinsic free wheeling diodes. Each channel includes two TTL/CMOS and uP compatible comparators, and a logic block to interface the inputs with the drivers. The device includes an internal bandgap reference of 1.22V, a 10V voltage reference to supply the internal circuitry of the device, a central charge pump to drive the upper DMOS switch, thermal shutdown protection and an internal hysteretic function which turns off the device when the junction temperature exceeds approximately 160 °C. Hysteresys is about 20 °C.
