STMicroelectronics VND5E025AKTR-E

Overview

VND5E025AKTR-E from STMicroelectronics is a dual-channel automotive high-side driver in PowerSSO-24 package, delivering 25 mΩ on-resistance per channel, 60 A current limiting (typ), 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 12 V vehicle systems.

For engineers reviewing the VND5E025AKTR-E datasheet, VND5E025AKTR-E pinout, VND5E025AKTR-E application, or VND5E025AKTR-E equivalent, key selection criteria include its integrated open-load detection (on/off-state), short-to-VCC diagnosis, thermal shutdown with auto-restart, and ±13% current sense ratio drift over -40 °C to 150 °C.

Technical Context

This device implements two independent VIPower M0-5 high-side switches with active power limitation for inrush and overload management. Each channel features dedicated analog current sense (CS1/CS2) with programmable disable (CS_DIS), enabling shared external sense resistor configurations.

Protection architecture includes undervoltage shutdown (4.5 V threshold), overvoltage clamp (up to 52 V), reverse-battery tolerance via external GND network, and thermal shutdown at 150 °C with 135 °C auto-restart hysteresis-ensuring robust operation under automotive transients per ISO 7637-2 and ISO 16750-2.

FAQ

What is the maximum continuous output current per channel?

The VND5E025AKTR-E does not specify a continuous current rating due to thermal dependence on PCB layout and ambient conditions. Its 60 A current limit is a short-circuit trip threshold; sustained current must be limited by thermal design to maintain junction temperature ≤150 °C. Typical continuous current is 10–15 A with 200 cm² copper area per channel, per Figure 36.

How does off-state open-load detection work?

Off-state open-load detection measures leakage current through the output MOSFET when the channel is disabled. If I_OUT < 5 µA (typ) with V_CC = 13 V and T_j = 25 °C, the device asserts an open-load condition via current sense pin behavior-verified in Table 10 and Figure 14. Detection time is <100 ms under specified conditions.

Can CS_DIS be used to multiplex current sense signals from multiple VND5E025AKTR-E devices?

Yes. Pulling CS_DIS high disables both current sense outputs (CS1 and CS2), allowing external circuitry to share a single sense resistor among multiple devices. The CS_DIS pin has CMOS-compatible thresholds (2.1 V high, 0.9 V low) and 0.25 V hysteresis, enabling clean digital control without additional level-shifting.

Is reverse-battery protection built-in or external?

Reverse-battery protection is external: the GND pin must be connected through a series diode or resistor network as shown in Section 3.1 of the datasheet. The device itself tolerates -0.3 V on VCC and includes internal ESD structures, but sustained reverse polarity requires external components to prevent damage to the substrate and parasitic paths.
