STMicroelectronics VND7140AJTR-E

Overview

VND7140AJTR-E from STMicroelectronics is a dual-channel smart high-side power switch in PowerSSO-16 package, designed for 12 V automotive loads with CMOS-compatible 3 V/5 V control inputs. It delivers 12 A current limit per channel, 140 mΩ typical on-state resistance, and integrates MultiSense analog feedback for load current, VCC, and chip temperature - used in body control modules for driving lamps and solenoids.

For engineers reviewing the VND7140AJTR-E datasheet, VND7140AJTR-E pinout, VND7140AJTR-E application, or VND7140AJTR-E equivalent, key selection criteria include diagnostic multiplexing capability (SEL0/SEL1-controlled), fault reset via active-low FaultRST, sense enable (S_EN), and thermal shutdown with configurable latch-off behavior.

Technical Context

The VND7140AJTR-E implements VIPower M0-7 technology to combine power switching and real-time diagnostics in a single die. Its two independent high-side channels support simultaneous operation with individual IN0/IN1 control, each featuring hysteresis and compatibility with 3 V/5 V logic levels.

Diagnostics are delivered through a single multiplexed analog output (MultiSense) that sequentially reports load current (via proportional current mirror), supply voltage, and junction temperature. Fault detection includes short-to-VCC, open-load in OFF-state, overload, and thermal shutdown - all configurable via dedicated pins (FaultRST, S_EN, SEL0/SEL1).

FAQ

What is the function of the FaultRST pin?

The FaultRST pin is an active-low input that unlatches the device after thermal shutdown or current-limit fault. When held low, it forces auto-restart mode; when pulsed low then released, it clears latched faults and resumes normal operation. It is CMOS-compatible with both 3 V and 5 V logic levels.

How does MultiSense work and what signals can it report?

MultiSense is a single-pin multiplexed analog current output. Using SEL0 and SEL1, users select between load current (proportional to I_OUT), VCC supply voltage, or internal chip temperature. Each signal is delivered as a precision current source, enabling accurate measurement with one external resistor and ADC channel.

Can VND7140AJTR-E drive inductive loads like solenoids or relays?

Yes - the device includes built-in protections essential for inductive loads: active current limitation, fast thermal transient self-limiting, overvoltage clamp, and OFF-state open-load detection. Its 12 A peak current limit and 140 mΩ R_ON ensure reliable switching of 12 V solenoids and relay coils without external flyback diodes.

Is an external sense resistor required for MultiSense operation?

No - MultiSense provides internal proportional current mirroring; only an external sensing resistor (R_SENSE) is needed if high-precision absolute current measurement is required. The evaluation board includes pads for either through-hole or SMD R_SENSE, but basic diagnostics operate without it using the internal reference.
