STMicroelectronics VN460SP13TR

Overview

VN460SP13TR from STMicroelectronics is a single-channel high-side smart solid-state relay designed for driving resistive or inductive loads with one side grounded. It delivers 25 A continuous output current at T_C = 25 °C, features 20 mΩ R_DS(on), 5 V logic-compatible input, and integrated open-drain diagnostic output for open-load and overtemperature detection. Used in industrial motor control and power distribution modules.

For engineers reviewing the VN460SP13TR datasheet, VN460SP13TR pinout, VN460SP13TR application, or VN460SP13TR equivalent, key selection criteria include thermal shutdown threshold (150–190 °C), under/overvoltage lockout (4 V / 39 V typ), diagnostic delay timing (50–950 µs), and PowerSO-10 package thermal resistance (1.1 °C/W junction-to-case).

Technical Context

The VN460SP13TR integrates vertical intelligent power technology with embedded protection circuitry including thermal shutdown, overvoltage and undervoltage lockout, and open-load detection. Its diagnostic output provides fault status via open-drain signaling with clamped voltage (−0.7 V to 7 V) and 1.6 mA sink capability.

Switching behavior is characterized by turn-on delay (25–250 µs), rise time (80–650 µs), and controlled di/dt (0.02–0.05 A/µs) during both turn-on and turn-off. The device supports ISO 7637-1 transient immunity up to Level IV across all pulses when used with ≥1 kΩ series resistors on input/status pins.

FAQ

What is the maximum continuous output current for VN460SP13TR?

The VN460SP13TR delivers 25 A continuous output current at case temperature (T_C) = 25 °C. Current rating decreases with rising case temperature due to thermal derating; at T_C = 85 °C, average short-circuit current is limited to 5.4 A per datasheet Section 4.4.

How does the open-load detection function work?

Open-load detection activates when V_CC is between 8–30 V and output current falls below 100–1500 mA. The STAT pin pulls low after a delay (t_POL = 50–950 µs) to indicate an open circuit. This function relies on internal current sensing and requires no external components.

Can VN460SP13TR be used in automotive applications?

While the VN460SP13TR meets ISO 7637-1 transient immunity requirements up to Level IV, ST explicitly states it is not designed or authorized for automotive applications per its product disclaimer. It lacks AEC-Q100 qualification and functional safety certification required for automotive use.

What is the purpose of the V_DEMAG parameter?

V_DEMAG specifies the clamp voltage applied to the OUT pin during inductive turn-off to limit flyback voltage. At V_CC = 13 V, V_DEMAG ≈ V_CC−55 V = −42 V; this protects the device from negative voltage spikes generated by inductive loads like solenoids or motors.
