STMicroelectronics VN750-B513TR

Overview

VN750-B513TR from STMicroelectronics is an automotive-grade high-side power switch in P2PAK package, designed for driving resistive, inductive, or capacitive loads with one side grounded. It features 60 mΩ R_DS(on), 6 A continuous output current, 36 V maximum supply voltage, and integrated open-load detection (on/off-state), short-circuit protection, and thermal shutdown. It is used in body control modules for lighting, solenoid, and relay drive applications.

For engineers reviewing the VN750-B513TR datasheet, VN750-B513TR pinout, VN750-B513TR application, or VN750-B513TR equivalent, key selection criteria include on-state resistance at 125 °C, ISO 7637-2 transient immunity (Class C up to Pulse 4), status pin diagnostic capability, and reverse battery protection architecture.

Technical Context

The device implements a VIPower® M0-3 monolithic BCD process with active V_CC clamp for low-energy spike suppression per ISO 7637-2. Its logic-compatible input accepts CMOS-level signals (V_IL ≤ 1.25 V, V_IH ≥ 3.25 V) and drives loads via a single N-channel DMOS output stage.

Diagnostic functionality includes dual-mode open-load detection: on-state current threshold (50–200 mA) and off-state voltage threshold (1.5–3.5 V), both reported through an open-drain status pin. Protection logic combines undervoltage (4 V typ.) and overvoltage (36 V) shutdown, thermal foldback at 150 °C, and ground-loss detection.

FAQ

What is the maximum safe operating temperature for VN750-B513TR?

The junction temperature is internally limited to 150 °C, with thermal shutdown activation at that point and automatic restart after cooling to 135 °C. Under continuous 6 A load with 6 cm² PCB copper, case temperature remains below 100 °C at 25 °C ambient, satisfying AEC-Q100 Grade 1 requirements (-40 to 125 °C ambient).

Does VN750-B513TR require an external pull-up resistor on the STATUS pin?

Yes - the STATUS pin is open-drain and requires an external pull-up (typically 4.7 kΩ to V_CC) to generate a valid logic-high signal during normal operation. Without it, the pin remains floating and cannot indicate healthy state reliably.

Can VN750-B513TR drive inductive loads like fuel injectors without external flyback protection?

Yes - its integrated output clamp limits demagnetization voltage to V_CC−41 V (min) during turn-off, safely absorbing energy from typical 12 V injector coils. This eliminates the need for external TVS or diode snubbers in most automotive applications.

How does the device detect open-load in off-state when the output is disconnected?

It applies a weak internal current source to the OUT pin and measures resulting voltage. If OUT rises above 1.5–3.5 V (depending on temperature), the STATUS pin asserts low - confirming absence of load path to ground, even with IN = low and no external bias.
