STMicroelectronics VN7007ALHTR

Overview

VN7007ALHTR from STMicroelectronics is a single-channel automotive-grade smart high-side driver in Octapak package, featuring 7 mΩ on-state resistance, 100 A current limitation, and analog CurrentSense feedback. It operates from 4–28 V supply, delivers <0.5 µA standby current, and drives grounded inductive/resistive loads (e.g., glow plugs, DC motors) via 3 V/5 V CMOS-compatible INPUT control.

For engineers reviewing the VN7007ALHTR datasheet, VN7007ALHTR pinout, VN7007ALHTR application, or VN7007ALHTR equivalent, key selection criteria include its AEC-Q100 qualification, integrated open-load/short-to-VCC diagnostics, configurable latch-off on overtemperature, and ±4000 V HBM ESD rating on critical pins.

Technical Context

The VN7007ALHTR integrates VIPower® technology to combine power MOSFET switching with real-time analog current sensing (KOL1 = 800 A/A), enabling precise load monitoring without external shunts. Its FR_DIAG pin controls fault latching behavior and enables OFF-state diagnostics including open-load detection via CS voltage thresholds.

Protection architecture includes active power limitation during overload, thermal shutdown at 150–200 °C with 7 K hysteresis, undervoltage lockout (4 V trip, 5 V reset), and bidirectional overvoltage clamping up to 46 V - all implemented within the monolithic die without external components.

Key Specifications

FAQ

What is the purpose of the FR_DIAG pin?

The FR_DIAG pin configures fault response behavior: when held low, it enables OFF-state open-load detection and sets latch-off mode; when pulled high, it enables auto-restart after fault clearance. It also serves as an input for diagnostic status reporting and must be externally biased per Table 3 - floating is not allowed.

Can VN7007ALHTR drive inductive loads without external flyback components?

Yes - VN7007ALHTR integrates active demagnetization clamping with V_DEMAG = V_CC − 41 V (typ.) and handles up to 170 mJ of switching energy per pulse. This eliminates the need for external freewheeling diodes or snubbers in most 12 V automotive inductive applications like solenoids and small DC motors.

How does the CurrentSense (CS) pin function during fault conditions?

During overload or short-to-ground, CS voltage drops to −12 V (clamped), signaling fault severity; during OFF-state open-load, CS rises to +7 V. These clamped levels provide unambiguous digital fault identification without additional signal conditioning, directly interfacing with MCU ADC or comparator inputs.

Is VN7007ALHTR compatible with 3.3 V microcontrollers?

Yes - the INPUT pin has VIH = 2.1 V min. and VIL = 0.9 V max. with 0.2 V hysteresis, ensuring reliable recognition of 3.3 V logic levels. The FR_DIAG pin shares identical thresholds, allowing full control and diagnostics using standard 3.3 V automotive MCUs without level-shifting circuitry.
