Características

  • 80mOhm low RDS(on) for minimal voltage drop at 3A
  • Comprehensive protection: thermal, overcurrent, short circuit, ESD
  • Open-drain diagnostic status output for fault detection
  • CMOS-compatible input with hysteresis for noise immunity
  • Undervoltage lockout prevents incomplete turn-on
  • AEC-Q100 qualified for automotive applications

Aplicaciones

  • Automotive lamp and solenoid driver

  • Distributed power distribution in vehicle body electronics
  • Building automation load switching

The VNS3NV04DPTR-E from STMicroelectronics is a monolithic single-channel high-side power switch using VIPower M0-3 technology in an SO-8 package. The device integrates a 30V N-channel power MOSFET with 80mOhm typical RDS(on) and all necessary control and protection circuitry. The 3A continuous output current rating supports a wide range of automotive and industrial loads including lamps, solenoids, relays, and heaters. Comprehensive protection features include thermal shutdown with automatic restart, current limitation with short-circuit protection, undervoltage lockout, and reverse battery protection. An open-drain diagnostic status output indicates fault conditions (overtemperature, overload, or open load) to the system MCU, enabling intelligent fault management. The CMOS-compatible input with hysteresis provides noise immunity in automotive environments. The device is AEC-Q100 qualified and supports 36V transient input voltage for load dump protection. The SO-8 package provides adequate thermal dissipation for the 3A rating with a thermal shutdown threshold at 150C typical.

The VNS3NV04DPTR-E uses a vertical power MOSFET with integrated control and protection. (1) High-Side Switch: The N-channel power MOSFET is connected between the supply (VCC) and the output (OUT). When the input (IN) is driven high, the charge pump generates a gate voltage above VCC to fully enhance the MOSFET, connecting VCC to OUT. When IN is low, the MOSFET turns off, disconnecting the load. (2) Charge Pump: An internal charge pump generates the gate drive voltage above the supply rail, enabling the use of N-channel MOSFETs for lower RDS(on) compared to P-channel alternatives. (3) Current Limit: If the output current exceeds the limit (typically 5-10A), the current limit circuit reduces the gate drive to regulate the current, preventing MOSFET damage. (4) Thermal Protection: A temperature sensor monitors the die temperature. If it exceeds approximately 150C, the MOSFET is turned off. When the die cools below the hysteresis threshold, the device automatically restarts. (5) Diagnostic: The status output is pulled low when a fault is detected (overtemperature or current limit active), providing real-time fault indication to the MCU.
