STMicroelectronics VNLD5300TR-E

Overview

VNLD5300TR-E from STMicroelectronics is an AEC-Q100 qualified, fully protected low-side driver IC for automotive resistive and inductive loads, featuring 2 A continuous drain current, 300 mΩ R_DS(on) at 25°C, 41 V overvoltage clamp, thermal shutdown with automatic restart, and SO-8 package. It drives solenoids, relays, and lamps in body control modules.

For engineers reviewing the VNLD5300TR-E datasheet, VNLD5300TR-E pinout, VNLD5300TR-E application, or VNLD5300TR-E equivalent, key selection criteria include diagnostic status reporting, fast demagnetization capability (3 µs turn-off delay), power limitation during overload, ESD robustness (5 kV HBM), and compliance with automotive EMC requirements.

Technical Context

The VNLD5300TR-E integrates two independent VIPower MOSFET channels in a single SO-8 package, each with CMOS-compatible input hysteresis, open-drain STATUS output, and internal protection logic. Its dual-channel architecture enables compact control of paired loads without external isolation.

Protection functions operate autonomously: overcurrent limiting activates within 7 µs, thermal shutdown triggers at 150–200°C junction temperature with 7°C hysteresis, and overvoltage clamping engages at 36 V threshold to suppress inductive kickback up to 41 V. The device maintains <10 µA standby current and exhibits low electromagnetic susceptibility per AEC-Q100.

Key Specifications

Pinout & Package

Delivered in SO-8 surface-mount package (4.9 mm × 6.0 mm × 1.75 mm), compliant with ECOPACK® RoHS and halogen-free standards. Thermal resistance junction-to-ambient is 115 °C/W on standard 2-layer FR4 PCB with footprint copper area.

FAQ

What is the maximum inductive load energy the VNLD5300TR-E can safely demagnetize?

The VNLD5300TR-E supports up to 26 mJ single-pulse avalanche energy (E_AS) at 150°C junction temperature with 19 mH inductance. For repetitive pulses, demagnetization energy must be limited based on starting junction temperature-e.g., ≤100 mJ at T_jstart = 100°C per Figure 6 in DS9083 Rev 9. Exceeding these limits risks triggering thermal shutdown.

How does the STATUS pin behave during overtemperature events?

During overtemperature, the STATUS pin transitions from high-impedance (pull-up driven) to active-low state within microseconds of thermal shutdown activation. It remains low until junction temperature falls below the reset threshold (T_R = T_TSD – 7°C). After reset, STATUS returns high only after normal operation resumes-no manual clearing is needed.

Can VNLD5300TR-E drive inductive loads directly without external freewheeling diodes?

Yes-the internal overvoltage clamp (41 V typical) and optimized die structure allow direct connection of inductive loads like solenoids and relays without external flyback diodes. However, for loads exceeding 19 mH or demanding ultra-fast decay, external snubbers may still be advised to manage peak clamp power dissipation.

What is the recommended series resistor value between MCU I/O and VNLD5300TR-E input pins?

ST recommends a 1 kΩ resistor (R_prot) between MCU I/O and IN1/IN2 to prevent latch-up during negative transients on the DRAIN pin. This value balances microcontroller I/O leakage current (<65 µA), input compatibility (VIH ≥ 1 V), and latch-up immunity (>20 mA threshold), as specified in Section 3.1 of DS9083 Rev 9.
