STMicroelectronics VND5E012MYTR-E

Overview

VND5E012MYTR-E from STMicroelectronics is a dual-channel automotive high-side driver in PowerSSO-36 package, delivering 12 mΩ on-resistance per channel, 74 A typical current limitation, and analog proportional current sense per output. It interfaces directly with 3 V/5 V CMOS microcontrollers to drive grounded resistive, inductive, or capacitive loads-including LED arrays-in engine control units and body electronics.

For engineers reviewing the VND5E012MYTR-E datasheet, VND5E012MYTR-E pinout, VND5E012MYTR-E application, or VND5E012MYTR-E equivalent, key selection criteria include its AEC-Q100 qualified thermal shutdown with auto-restart, reverse battery protection with self-switch-on, and ±8% current sense ratio drift over full temperature and load range-critical for functional safety–compliant diagnostics in 12 V automotive systems.

Technical Context

The device integrates two independent VIPower® M0-5 high-side switches with dedicated analog current sense (CS1/CS2) and a shared CS_DIS enable. Each channel features active power limitation during inrush/overload, overvoltage clamping at 41–52 V, and undervoltage shutdown at 3.5–4.5 V.

Diagnostic architecture delivers real-time load current feedback via externally scaled sense resistors, with fault indication through current sense disable timing (tDSENSE1H: 50–100 µs) and thermal shutdown status. Protection logic includes loss-of-ground and loss-of-VCC detection, plus self-limiting fast thermal transients.

FAQ

What is the maximum continuous output current per channel?

The VND5E012MYTR-E does not specify a fixed continuous current rating due to thermal dependence on PCB layout and ambient conditions. Its 74 A typical current limit (ILIMH) is a short-circuit threshold; sustained current must be derated based on R_thj-amb (up to 30°C/W depending on copper area) and maximum junction temperature of 150°C. For 10 A continuous operation, ≥200 cm² of 2 oz copper is recommended per channel.

How does the reverse battery protection function without external components?

The device integrates a dedicated reverse-polarity MOSFET that self-activates when VCC drops below -13 V, creating a low-impedance path to ground. This clamps reverse voltage across the load and internal circuitry while allowing normal forward operation - eliminating the need for external Schottky diodes or P-channel FETs and reducing total solution size by ~30 mm².

Can CS1 and CS2 be used simultaneously with a single external sense resistor?

No - CS1 and CS2 are independent current-sink outputs and cannot share one resistor without cross-talk. However, the CS_DIS pin allows disabling both channels' sense outputs simultaneously, enabling time-multiplexed use of a single external ADC input when paired with external analog switches or MCU-controlled sequencing - verified in ST Application Note AN4703.

Is the PowerSSO-36 package lead-free and RoHS compliant?

Yes - the VND5E012MYTR-E uses ST's ECOPACK®2 PowerSSO-36 package, certified to RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The exposed thermal pad is matte tin-plated, compatible with standard lead-free reflow profiles (peak 260°C, 40 s max), and qualified for automotive under JEDEC J-STD-020 moisture sensitivity level 3.
