STMicroelectronics VND7E050AJTR

Overview

VND7E050AJTR from STMicroelectronics is a dual-channel automotive high-side driver in PowerSSO-16 package, designed for 12 V grounded loads with CMOS-compatible 3 V/5 V control inputs. It delivers 50 mΩ typical on-state resistance per channel, 40 A current limitation, and supports deep cold cranking down to 2.85 V supply voltage. Used in ADAS radar power supplies and automotive lamp control with integrated CurrentSense analog feedback.

For engineers reviewing the VND7E050AJTR datasheet, VND7E050AJTR pinout, VND7E050AJTR application, or VND7E050AJTR equivalent, key selection criteria include cranking voltage margin (2.85 V), diagnostic multiplexing capability (CS/SEL0/SEn), latch-off configurability (FaultRST), and AEC-Q100 qualification for under-hood deployment.

Technical Context

The device integrates two independent VIPower® M0-7 high-side switches with shared diagnostic resources: a multiplexed current sense output (CS) controlled by SEL0 and enabled by SEn, supporting per-channel load current monitoring, open-load detection, short-to-VCC indication, and thermal shutdown reporting. Each channel features programmable fault response-latch-off or auto-restart-via FaultRST polarity configuration.

Protection architecture includes undervoltage shutdown (2.85 V), overvoltage clamp (41–52 V), dynamic current limiting (40 A typ.), and self-limiting thermal transients with 150 °C shutdown threshold and 7 °C hysteresis. Standby current remains ≤0.5 µA at 13 V and 25 °C, enabling always-on module designs compliant with LV124 Rev. 2013.

FAQ

What is the purpose of the FaultRST pin?

The FaultRST pin configures fault recovery behavior: pulling it low unlatches a latched fault condition, while holding it low enables auto-restart mode during overload. It does not reset the device but controls whether the output remains off (latch-off) or cycles on/off (auto-restart) after thermal or current-limit events. Its active-low CMOS compatibility ensures direct interfacing with standard microcontroller GPIOs.

How does the CurrentSense multiplexer work with SEL0 and SEn?

SEn must be high to activate the CS pin; SEL0 then selects which channel's diagnostic data appears on CS - SEL0 = low routes Channel 0 current, SEL0 = high routes Channel 1 current. When both channels are active, only one is reported at a time. This allows sharing of a single external sense resistor and ADC input across both channels, reducing system cost and layout complexity.

Can VND7E050AJTR drive inductive loads like fuel injectors?

Yes - it is explicitly characterized for inductive loads with turn-off energy clamping (V_DEMAG = V_CC − 41 V at 25 °C) and fast transient thermal limiting. The datasheet specifies switching energy losses (W_OFF ≤ 1 mJ) and dynamic temperature rise limits (ΔT_{J_SD} = 60 K), confirming suitability for repetitive solenoid actuation without external snubbers in most 12 V automotive applications.

Is external reverse-battery protection required on GND?

Yes - the GND pin must be protected against reverse battery conditions using an external diode or resistor network as specified in the datasheet. The device itself does not integrate reverse-polarity protection on GND; failure to implement this external protection risks permanent damage during service or jump-start scenarios where battery terminals are reversed.
