STMicroelectronics VNP5N07

Overview

VNP5N07 from STMicroelectronics is a fully autoprotected monolithic VIPower M0 high-side power switch, integrating linear current limiting (5 A), overvoltage clamp (70 V), thermal shutdown (150 °C), diagnostic feedback via input pin, and direct gate access for analog driving. It replaces standard N-channel MOSFETs in DC–50 kHz inductive load switching applications such as automotive solenoid drivers and industrial relay controls.

For engineers reviewing the VNP5N07 datasheet, VNP5N07 pinout, VNP5N07 application, or VNP5N07 equivalent, key selection criteria include its integrated fault detection capability, 0.2 Ω R_DS(on) at 10 V_IN, 31 W T_C = 25 °C power dissipation, and compatibility with TTL-level logic drive without external level-shifting.

Technical Context

The VNP5N07 implements a high-side configuration with internal gate driver and protection circuitry co-integrated on a single die using ST's VIPower M0 process. Its input pin directly controls the power MOSFET gate but also sinks fault current (50 mA) when thermal or overcurrent conditions trigger, enabling real-time diagnostics without additional sensors.

Protection functions operate independently of input voltage: current limiting activates at 3.5–7 A depending on V_IN, clamping engages at 55–80 V (typ. 70 V), and thermal shutdown/reset thresholds are fixed at 150 °C / 135 °C. The device supports unclamped inductive switching with 0.2 J single-pulse avalanche energy rating.

FAQ

What is the maximum operating frequency for PWM switching with the VNP5N07?

The VNP5N07 is characterized for DC to 50 kHz operation per datasheet. At 50 kHz, its 100 ns typical fall time and 18 nC input charge allow efficient switching with standard 10 Ω gate drivers. Higher frequencies increase switching losses and require careful thermal design due to limited 31 W T_C = 25 °C dissipation.

Can the VNP5N07 be used in low-side configuration?

No - the VNP5N07 is internally configured as a high-side switch only. Its source terminal is referenced to system ground, and the drain connects to the load. Attempting low-side use would reverse internal protection circuitry and disable fault feedback, violating absolute maximum ratings and voiding protection functionality.

How does the diagnostic feedback signal work during overtemperature fault?

During overtemperature fault, the internal protection disconnects the input pin from the gate and connects it to ground via ~100 Ω. This pulls the input voltage near 0 V when driven by a high-impedance source (e.g., MCU GPIO with pull-up), enabling simple voltage-level detection without additional circuitry.

Is an external flyback diode required when driving inductive loads?

No - the integrated 70 V overvoltage clamp and 0.2 J avalanche energy rating enable safe unclamped inductive switching. However, for highly repetitive or high-energy inductive loads (e.g., >100 mJ), an external TVS or RC snubber may extend lifetime by reducing stress on the internal clamp structure.
