STMicroelectronics VND5E004C30-E

Overview

VND5E004C30 from STMicroelectronics is a dual-channel AEC-Q100 qualified high-side driver for 12 V automotive grounded loads, featuring 4 mΩ on-state resistance per channel, analog current sense with ±14% ratio drift over temperature, and integrated diagnostics including off-state open-load and short-to-VCC detection. It operates from 4.5–28 V, supports 3 V/5 V CMOS inputs, and delivers 90 A typical current limiting for inductive/resistive/capacitive loads in body control modules.

For engineers reviewing the VND5E004C30 datasheet, VND5E004C30 pinout, VND5E004C30 application, or VND5E004C30 equivalent, key selection criteria include thermal shutdown auto-restart behavior, proportional current sense accuracy across –40 °C to 150 °C, diagnostic enable (DE) timing response (50–100 µs), and MultiPowerSO-30 package thermal resistance (0.35 °C/W junction-to-case).

Technical Context

The device implements ST's VIPower® M0-5 technology with dual independent high-side power switches, each integrating active power limitation for overload/short-circuit protection and real-time thermal monitoring with auto-restart after overtemperature shutdown. Its analog current sense architecture uses dedicated CS1/CS2 pins delivering I_SENSE = I_OUT/K₀, where K₀ = 12130 typ. at 25 °C and varies by ±14% over full temperature range.

Diagnostic functions are controlled via the DE pin: when high, it enables proportional current sensing and fault reporting (power limitation, overtemperature, open-load); when low, it disables sensing to share external sense resistors. Protection includes reverse battery self-switch-on, undervoltage shutdown (4.5 V threshold), and V_CC clamp at 46 V (typ.), all compliant with ISO 7637-2 load dump requirements.

FAQ

What is the maximum transient voltage the VND5E004C30 can withstand on VCC?

The VND5E004C30 supports a maximum transient supply voltage of 41 V for durations under 400 ms with load resistance > 0.5 Ω. Its internal overvoltage clamp activates at 46 V (typical), protecting against ISO 7637-2 load dump pulses without external components. This rating is validated per AEC-Q100 stress testing protocols and applies across the full operating temperature range.

How does the analog current sense function during thermal shutdown?

During thermal shutdown, the VND5E004C30 maintains active current sense output on CS1/CS2 pins, delivering I_SENSE proportional to actual load current until junction temperature exceeds 200 °C. The device also asserts a fault condition by driving V_SENSE to 8 V (typical) when overtemperature occurs, enabling immediate MCU intervention before latch-off.

Can the DE pin be left floating in the VND5E004C30?

No, the DE pin must not be left floating. Per ST's recommended connections, DE should be pulled high to VCC via a 10 kΩ resistor for normal diagnostic operation. Floating DE causes undefined behavior in current sense activation and fault reporting; the datasheet explicitly prohibits unconnected DE and specifies minimum 2.1 V high-level voltage for reliable enable function.

What is the thermal resistance of the MultiPowerSO-30 package in standard PCB layout?

The MultiPowerSO-30 package achieves 0.35 °C/W junction-to-case thermal resistance with one channel active, measured using a 58 mm × 58 mm FR4 PCB with 2 mm thickness and 35 µm copper. Junction-to-ambient resistance is 58 °C/W under same conditions, enabling 150 °C junction operation at 13 V/15 A with appropriate copper pour and thermal vias.
