STMicroelectronics VN460SP-E

Overview

VN460SP-E 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.

For engineers reviewing the VN460SP-E datasheet, VN460SP-E pinout, VN460SP-E application, or VN460SP-E equivalent, key selection criteria include its thermal shutdown threshold (150–190 °C), under/overvoltage lockout (4 V / 39 V typ.), status delay timing (50–950 µs), and ISO 7637-2 pulse immunity up to Level IV.

Technical Context

The VN460SP-E integrates vertical intelligent power technology with embedded protection circuitry including thermal shutdown, overcurrent limiting, and voltage-dependent fault detection. Its diagnostic output asserts low during open-load (V_CC ≥ 8 V) or overtemperature conditions, with programmable delay (t_POL/t_POVL) and clamped status pin voltage (−0.7 to 7 V).

It operates across V_CC = 5.5–36 V, supports 5 V CMOS logic input with 0.85 V hysteresis, and exhibits fast switching (t_r = 80–650 µs, t_f = 80–400 µs) with controlled di/dt (0.02–0.05 A/µs) to reduce EMI in automotive-grade load control.

FAQ

What is the maximum continuous output current and under what thermal condition?

The VN460SP-E delivers 25 A continuous output current at case temperature (T_C) = 25 °C. Current derating applies above this temperature per the thermal resistance curve (R_thj-case = 1.1 °C/W max); at T_C = 85 °C, maximum continuous current drops to approximately 12 A based on junction temperature limit of 150 °C.

How does the open-drain STAT output indicate fault conditions?

The STAT pin pulls low during open-load detection (when load current < 100 mA and V_CC ≥ 8 V) or thermal shutdown (T_J ≥ 150 °C). It remains high otherwise. An external pull-up resistor (typically 10 kΩ to V_CC) is required; the pin is clamped to −0.7 V to 7 V and tolerates ±10 mA sink/source current.

Is the VN460SP-E qualified for automotive applications?

No-ST explicitly states in the datasheet that the VN460SP-E is not designed or authorized for automotive, safety-critical, or life-support applications. While it meets ISO 7637-2 transient immunity requirements, it lacks AEC-Q100 qualification and functional safety certification (e.g., ISO 26262 ASIL), and is marked "Obsolete Product(s)" in Rev 3 documentation.

What external components are required for basic operation?

Only three external components are mandatory: a 10 kΩ pull-up resistor on the STAT pin, a ≥1 kΩ series resistor on the IN pin for ISO 7637-2 Pulse 5 compliance, and a ≥1 kΩ series resistor on the STAT pin for same compliance. No external flyback diode is needed due to the integrated V_DEMAG clamp, and no gate resistor is required for the internal MOSFET.
