Texas Instruments’ SM72295 is a Photovoltaic Full-Bridge Driver

This post sponsored by Texas Instruments.

The SM72295 is designed to drive four discrete N-type MOSFETs in a full-bridge configuration.

The drivers provide 3A of peak current for fast, efficient switching and integrated high-speed bootstrap diodes. Current sensing is provided by two transconductance amplifiers with externally programmable gain and filtering to remove ripple current, and to provide average current information to the control circuit. The current-sense amplifiers have buffered outputs available to provide a low impedance interface to an A/D converter if needed. An externally programmable input-over-voltage comparator is also included to shut down all outputs. Under-voltage lockout with a PGOOD indicator prevents the drivers from operating if VCC is too low. The SM72295 features renewable energy grade and 100V bootstrap diodes, as well as independent high and low driver logic inputs. The device is available in a SOIC-28 package. It may be used in the following applications: automotive and transportation; communications and telecom; computers and peripherals; consumer electronics; energy and lighting; industrial; medical; security;, space, avionics, and defense; and video and imaging.
