STMicroelectronics VN750PT13TR

Overview

VN750PT13TR from STMicroelectronics is an automotive-grade high-side power switch IC in PPAK package, designed to drive grounded loads with 60 mΩ R_DS(on), 6 A continuous output current, and 36 V supply voltage rating. It integrates on-state/off-state open-load detection, short-circuit protection, undervoltage/overvoltage shutdown, reverse battery protection, and thermal shutdown-enabling robust load control in vehicle body electronics.

For engineers reviewing the VN750PT13TR datasheet, VN750PT13TR pinout, VN750PT13TR application, or VN750PT13TR equivalent, key selection criteria include its AEC-Q100 qualification, diagnostic status pin functionality, ISO 7637-2 transient immunity (Class C for pulses 1–4), and PPAK thermal performance (R_thj-amb = 37 °C/W on 6 cm² copper).

Technical Context

The VN750PT13TR implements a monolithic VIPower® M0-3 high-voltage DMOS output stage with integrated CMOS logic input stage and analog diagnostics. Its active VCC clamp handles low-energy transients per ISO 7637-2, while current limitation (6–15 A) combines with thermal shutdown (T_TSD = 150–200 °C) and automatic restart for overload resilience.

Diagnostic capability centers on the STATUS pin: it outputs open-drain logic-low during normal operation, asserts high-impedance during overtemperature or undervoltage, and pulls low during overvoltage or off-state open-load detection. Input hysteresis (0.5 V) and CMOS-compatible thresholds (V_IL = 1.25 V, V_IH = 3.25 V) ensure noise-immune digital control.

FAQ

What is the maximum safe operating temperature for VN750PT13TR?

The VN750PT13TR has a junction temperature limit of 150 °C for continuous operation, with thermal shutdown activating at 150–200 °C depending on stress conditions. Its PPAK package achieves R_thj-amb = 37 °C/W on 6 cm² copper, enabling 6 A operation at T_amb ≤ 85 °C without forced cooling. Derating curves in the datasheet define precise current limits versus ambient temperature.

Does VN750PT13TR require an external pull-up resistor on the STATUS pin?

Yes, the STATUS pin is open-drain and requires an external pull-up resistor (typically 4.7 kΩ to V_CC) to generate valid logic-high signals during fault conditions. Without it, the pin remains floating during overtemperature, undervoltage, or overvoltage events-preventing reliable fault detection by the host microcontroller.

Can VN750PT13TR drive inductive loads like solenoids or relays?

Yes, it is explicitly designed for inductive loads. The device includes active demagnetization clamping (V_demag = V_CC − 41 V to V_CC − 55 V) and supports up to 138 mJ switching energy (L = 2.46 mH). For optimal reliability, use snubber networks or freewheeling diodes per ST's application note AN4023 when driving highly inductive or high-energy loads.

How does VN750PT13TR detect open-load conditions in the off-state?

In off-state, the device applies a small test current through the output and measures voltage at OUT. If V_OUT exceeds 1.5–3.5 V (depending on temperature), it confirms an open circuit and pulls STATUS low after 1000 µs delay. This works even with no external pull-up, as the internal current source creates a measurable voltage drop across the open path.
