STMicroelectronics VND5E050ACJTR-E

Overview

VND5E050ACJTR-E from STMicroelectronics is a dual-channel high-side driver IC for 12 V automotive grounded loads, featuring integrated analog current sense per channel, 50 mΩ on-state resistance, 27 A typical current limitation, and CMOS-compatible 3.0 V/5.0 V inputs. It delivers diagnostic feedback (open-load, short-to-VCC, overtemperature, overload) and protection (undervoltage shutdown, overvoltage clamp, reverse-battery tolerance) in PowerSSO-12 packaging.

For engineers reviewing the VND5E050ACJTR-E datasheet, VND5E050ACJTR-E pinout, VND5E050ACJTR-E application, or VND5E050ACJTR-E equivalent, key selection criteria include per-channel current sense ratio stability (±15% over -40°C to +150°C), thermal shutdown auto-restart behavior, PowerSSO-12 thermal resistance (2.7 °C/W junction-to-case), and CS_DIS pin functionality for shared external sense resistor architectures.

Technical Context

This device implements two independent VIPower® M0-5 high-side switches with active power limitation for inrush and overload management, enabling stable drive of resistive, inductive, and capacitive automotive loads without external current limiting. Each channel integrates dedicated analog current sense with programmable disable via CS_DIS, supporting precise real-time load monitoring across wide current ranges (50 mA–27 A).

Protection architecture includes undervoltage lockout (4.5 V threshold), overvoltage clamp (41–52 V), self-limiting fast thermal transients, and loss-of-ground/VCC detection. Diagnostic outputs provide discrete status signals-short-to-VCC, off-state open-load, and thermal shutdown-with defined delay timing (e.g., 10 µs typical open-load detection delay).

FAQ

What is the function of the CS_DIS pin?

The CS_DIS pin is an active-high CMOS input that disables both analog current sense channels simultaneously. When pulled high (≥2.1 V), it disconnects the internal sense transistors, allowing external sharing of a single precision sense resistor across multiple VND5E050ACJTR-E devices-reducing system-level component count and board area in multi-channel designs.

Does VND5E050ACJTR-E support 3.3 V microcontroller interfaces?

Yes. The INPUT1 and INPUT2 pins are fully compatible with 3.0 V CMOS logic levels: VIH is specified at 2.1 V minimum and VIL at 0.9 V maximum, with 0.25 V hysteresis. This ensures reliable switching with standard 3.3 V MCUs without level-shifting circuitry, even under automotive voltage transients and temperature extremes.

How does the device handle reverse battery conditions?

VND5E050ACJTR-E tolerates -0.3 V on the VCC pin but requires external reverse-battery protection on the GND pin per ST's recommended network (Fig. 31): either a series resistor (RGND) or Schottky diode (DGND) between PCB GND and IC GND. This configuration prevents latch-up and damage during accidental battery polarity reversal in service environments.

What thermal derating applies above 100°C ambient?

With one channel active and mounted on a 25 cm² copper area (2 oz), R_thj-amb is ~35 °C/W (Fig. 36). At 100°C ambient, maximum continuous output current drops to ~3.5 A to maintain T_j ≤ 150°C. Derating is linear: every 10°C ambient rise reduces usable current by ~0.5 A. Full thermal models are provided in Section 4.1 of the datasheet.
