STMicroelectronics VND5E025BK-E

Overview

VND5E025BK-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 limitation (typ), and analog current sense with ±9.5% single-point calibration drift. It drives grounded 12V resistive/inductive/capacitive loads-including LED blinkers-with CMOS-compatible 3V/5V inputs and integrated thermal shutdown with auto-restart.

For engineers reviewing the VND5E025BK-E datasheet, VND5E025BK-E pinout, VND5E025BK-E application, or VND5E025BK-E equivalent, key selection criteria include its dual-channel high-side topology, 4.5–28 V operating range, reverse-battery protection capability, and dedicated CS_DIS pin for shared current-sense resistor management in multi-driver systems.

Technical Context

The device implements two independent VIPower™ M0-5 high-side switches with active power limitation for inrush and overload control, each featuring a dedicated analog current sense output (CS1/CS2) referenced to GND and scalable via external resistor. Diagnostic feedback includes fast short-to-ground detection via current-sense delay (tDSENSE2H ≤ 300 µs) and thermal shutdown indication with 150°C trip point and 135°C reset.

Protections include undervoltage shutdown (4.5 V threshold), overvoltage clamp (up to 46 V), self-limiting fast thermal transients, loss-of-ground/loss-of-VCC detection, and ESD robustness (4 kV HBM on inputs). The CS_DIS pin enables synchronous disable of both current sense channels, supporting shared sensing architecture in clustered load-driving configurations.

FAQ

What is the maximum continuous output current per channel?

The VND5E025BK-E does not specify a fixed continuous current rating; instead, it uses active power limitation to sustain 60 A short-circuit current (typ) while maintaining safe junction temperature. Continuous current depends on PCB copper area, ambient temperature, and thermal design-e.g., 8 A per channel is achievable with ≥200 cm² 2-oz copper in free air per Figure 33.

How does the current sense ratio drift affect calibration accuracy?

dK/K_tot of ±9.5% means that calibrating at 2.4 A and 25°C yields worst-case error of ±9.5% across full temperature and current range. For higher accuracy, a two-point calibration (e.g., at 0.5 A and 3 A) reduces residual error to <±1.5%, as shown in Table 9's dK1/K1 through dK6/K6 data.

Can CS_DIS be used to multiplex current sense signals from multiple VND5E025BK-E devices?

Yes-driving CS_DIS high disables both CS1 and CS2 outputs, placing them in high-impedance state. This allows multiple VND5E025BK-E devices to share a single external sense resistor and ADC input, provided timing synchronization is managed externally to avoid contention during sense-enable transitions.

Is reverse battery protection internal or external?

Reverse battery protection is not fully internal: the device tolerates reverse V_CC down to -0.3 V (Table 3), but GND pin requires external protection (diode or resistor network per Section 3.1) to survive full -14 V reverse battery condition. The integrated protection covers only V_CC-to-GND polarity reversal, not GND-to-chassis inversion.
