STMicroelectronics VND5E160AJTR-E

Overview

VND5E160AJTR-E from STMicroelectronics is a dual-channel high-side driver IC for 12V automotive grounded loads, featuring analog current sense per channel, 160 mΩ typical on-resistance, 10 A current limitation, and integrated diagnostics including open-load detection, short-to-VCC/ground indication, and thermal shutdown with auto-restart. It operates from 4.5 V to 28 V and supports 3.0 V CMOS-compatible microcontroller interfacing in body control modules.

For engineers reviewing the VND5E160AJTR-E datasheet, VND5E160AJTR-E pinout, VND5E160AJTR-E application, or VND5E160AJTR-E equivalent, key selection criteria include its PowerSSO-12 package thermal performance, ±13% current sense ratio drift over temperature, dual-channel independent fault reporting, and reverse-battery protection compatibility per application schematic.

Technical Context

This device implements two independent VIPower M0-5 high-side switches with active power limitation for inrush and overload management. Each channel integrates a proportional analog current sense path (K₀ = 270–730), CS_DIS-controlled disable capability, and dedicated diagnostic flags for off-state open load, short-to-VCC, and thermal shutdown.

The protection architecture combines undervoltage lockout (4.5 V threshold), overvoltage clamp (41–52 V), self-limiting fast thermal transients, and loss-of-ground/VCC detection. Diagnostic outputs are analog (current sense) and digital (STATUS pin implied via fault latching logic), not PWM or SPI.

FAQ

What is the maximum continuous output current per channel?

The VND5E160AJTR-E does not specify a continuous current rating; instead, it uses active power limitation to cap short-circuit current at 10 A typ. Continuous operation depends on PCB thermal design and ambient temperature. At 25°C ambient with 10 cm² copper area, max continuous current is ~5.5 A per channel before thermal shutdown activates.

How does the current sense function behave during thermal shutdown?

During thermal shutdown, the current sense output remains active and reflects actual load current until junction temperature reaches 150°C, then transitions to fault state (ISENSE ≈ 9 mA) as defined in Table 9. This allows the MCU to distinguish between overload and true thermal shutdown events using the same analog input.

Can CS_DIS be used to dynamically enable/disable current sensing during operation?

Yes. Asserting CS_DIS high disables both current sense channels within 100 µs (t_DSENSE1H), halting analog output and reducing sense leakage to <1 µA. This enables time-multiplexed sensing across multiple VND5E devices sharing one external sense resistor and ADC input.

Is the PowerSSO-12 package RoHS-compliant and lead-free?

Yes. The PowerSSO-12 package carries ECOPACK®2 certification, confirming full compliance with EU Directive 2011/65/EU (RoHS2) and lead-free soldering compatibility up to 260°C peak reflow temperature, as documented in Section 5.1 of the datasheet.
