STMicroelectronics VND600PEPTR-E

Overview

VND600PEPTR-E from STMicroelectronics is a dual-channel high-side power switch IC designed for automotive and industrial resistive/inductive load control with ground-referenced loads. It features 30 mΩ R_DS(on) per channel, 25 A DC short-circuit current limit, proportional current sense (K ≈ 4400), and integrated protections including thermal shutdown, overvoltage clamp (41–55 V), undervoltage lockout (4 V typ), and reverse battery tolerance. It is used in body control modules for headlight, fog light, and HVAC blower drive.

For engineers reviewing the VND600PEPTR-E datasheet, VND600PEPTR-E pinout, VND600PEPTR-E application, or VND600PEPTR-E equivalent, key selection criteria include channel independence, analog current sense accuracy (±10% ratio drift), PowerSSO-24 thermal performance (R_thj-case = 1.3 °C/W dual-channel), ISO 7637-2 transient immunity (Class C up to Pulse 4), and GND/VCC loss detection capability.

Technical Context

This device implements two independent VIPower™ M0-3 high-side switches in a single PowerSSO-24 package, each with CMOS-compatible digital inputs, dedicated analog current sense outputs (VSENSE1/VSENSE2), and autonomous protection logic. The on-state resistance is specified at 30 mΩ (T_j = 25°C) and rises to 100 mΩ at T_j = 150°C, enabling precise thermal-aware current limiting.

Protection functions operate autonomously: thermal shutdown triggers at 150–200°C with 15°C hysteresis; overvoltage shutdown activates at 36 V; undervoltage shutdown occurs below 4 V; and reverse-battery operation is supported via internal clamping and external GND-network design guidance (e.g., DGND diode + 1 kΩ resistor). All protections feed status into the truth table-defined output behavior without MCU intervention.

FAQ

What is the maximum continuous output current per channel under typical PCB thermal conditions?

The VND600PEPTR-E supports 25 A DC short-circuit current limit per channel, but continuous current depends on thermal design. With 8 cm² copper on FR-4, R_thj-amb = 39 °C/W allows ~7.5 A continuous at T_c = 100°C (ΔT = 50°C). Derating curves in Figure 15 confirm 15 A max at T_case = 85°C with proper heatsinking.

How does the current sense output behave during thermal shutdown?

During thermal shutdown (T_j ≥ 150°C), the output turns OFF and the sense pin drives VSENSEH ≈ 5.5 V (per Table 9), signaling overtemperature via fixed high-level voltage-distinct from normal proportional output-enabling immediate software response without calibration.

Can unused input pins be left floating, and what is the recommended treatment for unused sense pins?

Unused input pins (IN1/IN2) may be left unconnected per Table 2. Unused sense pins (ISENSE1/ISENSE2) must be connected directly to GND to prevent floating node instability and ensure predictable protection behavior during fault conditions.

What external components are required for reverse battery protection in automotive applications?

A series diode (DGND) in the ground path plus a parallel 1 kΩ resistor is recommended per Section 3.1.2. This network limits reverse current to <200 mA (within absolute max rating) and shifts input thresholds by ≤600 mV-acceptable for most 3.3 V/5 V MCUs with appropriate input resistor sizing.
