NCV7708DW

Overview

The NCV7708DW is a double hex half-bridge driver manufactured by onsemi, designed for automotive applications. It integrates six independent half-bridge drivers in a single package, featuring an SPI interface for control and configuration. The device supports a supply voltage range of 3V to 5.25V and can drive loads up to 40V. It delivers an output current of 500mA per channel and operates within a junction temperature range of -40°C to 150°C. Packaged in a 28-SOIC surface-mount case, it is built with power MOSFET technology.

Feature Summary

• Integrates six independent half-bridge drivers for comprehensive motor control
• Utilizes Serial Peripheral Interface (SPI) for digital communication and configuration
• Built-in protection mechanisms against overcurrent, overtemperature, and short circuits
• Automotive-grade qualification ensuring reliability in harsh environments

Applications

• Brushed DC motor control systems
• Stepper motor driving applications
• General-purpose motor control in automotive electronics
