Fully-protected MOSFET drivers deigned to control a variety of loads

21 February 2007 Power Electronics / Power Management

ON Semiconductor has introduced two new drivers specifically designed for robust automotive and industrial applications. The NCV7513 is a programmable six channel low-side MOSFET pre-driver, designed to control a variety of load types. The NCV7708 is a hex half-bridge driver specifically designed to drive power system motors and loads.

"From lamps to relays and motors to LEDs, these devices offer a cost effective solution for driving a wide variety of loads," explains Jim Alvernaz, director of ON Semiconductor's Automotive Power Products Division. "They also feature the communications and diagnostics capabilities needed in today's safety conscious vehicles."

The NCV7513 is a fully-protected six channel low-side Hex Pre-Driver designed for a wide variety of loads, including engine control, memory seats and LED headlamps. This device is the newest member of a growing family of FLEXMOS automotive-grade products for driving logic level MOSFETs.

The NCV7513 is controllable by a combination of serial peripheral interface (SPI) and parallel inputs. With 3,3 V and 5,0 V compatible inputs, it is well-suited for use with the newer microcontrollers. Each of the six channels independently monitors its external MOSFETs for fault conditions. It features programmable fault management modes and allows power-limiting pulse width modulation (PWM) operation. The fault information for each channel is uniquely captured by fault type.

The NCV7708 is a fully-protected hex half bridge driver and the newest member of a family of multichannel drivers. The device features six independent high side and six independent low side drivers that are also configurable as H-bridge drivers. This device is controlled via SPI up to 5 MHz. It offers advanced fault reporting and protection features, and is compliant with 5 V and 3,3 V systems.
