STMicroelectronics VN460SPTR-E

Overview

VN460SPTR-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 typical R_DS(on), 5 V logic-compatible input, and integrated open-drain diagnostic output for open-load and overtemperature detection.

For engineers reviewing the VN460SPTR-E datasheet, VN460SPTR-E pinout, VN460SPTR-E application, or VN460SPTR-E equivalent, key selection criteria include thermal shutdown threshold (150–190 °C), under/overvoltage protection (4 V / 39 V typ), status delay timing (50–950 µs), and PowerSO-10 package thermal resistance (1.1 °C/W junction-to-case).

Technical Context

The device implements vertical intelligent power technology with monolithic integration of power MOSFET, driver, protection circuitry, and diagnostics. Its control architecture includes hysteresis-enabled 5 V CMOS-compatible input (V_IL = 1.5 V, V_IH = 3.5 V) and clamped input voltage (6 V max), enabling direct microcontroller interfacing without external level-shifting.

Protection functions operate autonomously: under-voltage lockout (4 V typ), overvoltage shutdown (39 V typ), thermal shutdown (150–190 °C), and open-load detection (V_ENOL = 6.6 V typ). The open-drain STATUS pin reports fault conditions with defined delay (t_POL = 50–950 µs, t_POVL = 10 µs) and clamp limits (−0.7 to 7 V).

FAQ

What is the maximum continuous output current for VN460SPTR-E?

The VN460SPTR-E delivers 25 A continuous output current at case temperature T_C = 25 °C. Current capability decreases with rising case temperature due to thermal derating; at T_C = 85 °C, average short-circuit current is specified at 5.4 A. Proper heatsinking using the exposed PowerSO-10 thermal pad is required to sustain rated current.

Does VN460SPTR-E support 3.3 V logic input levels?

No - the VN460SPTR-E requires a minimum input high voltage of 3.5 V (typical) and has 1.5 V input low threshold, making it incompatible with standard 3.3 V logic without level translation. Its input is explicitly designed for 5 V CMOS compatibility, with internal clamping to 6 V and ±10 mA absolute maximum input current.

How does the STATUS pin indicate open-load condition?

The STATUS pin asserts low (≤0.4 V at 1.6 mA sink) after a programmable delay of 50–950 µs (t_POL) when V_CC is between 8 V and 30 V and no load current is detected. This occurs only when the output is enabled and V_ENOL threshold (5.2–8 V) is exceeded, confirming absence of load connection or excessive load resistance.

Can VN460SPTR-E be used in automotive applications despite its "Obsolete" status in ST documentation?

Yes - while ST marked VN460SPTR-E as obsolete in 2013, Aetrix Electronics maintains active inventory and supply chain support for legacy industrial and automotive programs requiring drop-in replacement. Its ISO 7637-2 Pulse 2a/5 compliance, thermal robustness, and diagnostic features remain validated for non-safety-critical body electronics and chassis modules.
