Description

The IXDP610 Digital Pulse Width Modulator (DPWM) is a programmable CMOS LSI device which accepts digital pulse width data from a microprocessor and generates two complementary, non-overlapping, pulse width modulated signals for direct digital control of switching power bridge. The DPWM is designed to be operated under the direct control of a microprocessor and interfaces easily with most standard microprocessor and microcomputer buses. The IXDP610 is packaged in an 18-Pin slim DP.

Features

● Microcomputer bus compatible

● Two complementary outputs for direct control of a switching power bridge

● Dynamically programmable pulse width ranges from 0 to 100

● Two modes of operation: 7-bit or 8- bit resolution

● Switching frequency range up to 390 kHz

● Programmable Dead-time Counter prevents switching overlap

● Cycle-by-Cycle disable input to protect against over-current, overtemperature, etc.

● Outputs may be disabled under software control

● Special locking bit prevents damage to the stage in the event of a software failure

● 18-pin slim DIP package
