STMicroelectronics VND5E050MJTR-E

Overview

VND5E050MJTR-E from STMicroelectronics is a double-channel high-side driver IC for automotive 12 V grounded loads, featuring integrated analog current sense per channel, 50 mΩ typical on-state resistance, 27 A typical current limitation, and 4.5–28 V operating supply range. It delivers diagnostic feedback, thermal shutdown with auto-restart, reverse-battery protection support, and CMOS-compatible 3 V/5 V inputs - used in body control modules to drive solenoids, relays, and LED arrays.

For engineers reviewing the VND5E050MJTR-E datasheet, VND5E050MJTR-E pinout, VND5E050MJTR-E application, or VND5E050MJTR-E equivalent, key selection criteria include channel-wise current sense accuracy (±15% ratio drift over temperature), PowerSSO-12 package thermal resistance (2.7 °C/W junction-to-case), and ISO/TS 16949–qualified overload protection behavior under transient load conditions.

Technical Context

The device implements dual independent VIPower™ M0-5 high-side switches with active power limitation during inrush and short-circuit events, using internal voltage clamping (41–52 V) and thermal foldback to sustain 27 A peak without external intervention. Each channel integrates dedicated current sense circuitry with programmable disable via CS_DIS pin.

Protections include undervoltage shutdown (4.5 V threshold), overtemperature shutdown (150–200 °C trip range), loss-of-ground and loss-of-VCC detection, and ESD robustness (4 kV HBM on IN/CS pins). Diagnostic outputs provide proportional I_OUT/I_SENSE ratios across 0.05–4 A load range with temperature-compensated gain stability.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous output current per channel?

The device does not specify a continuous current rating due to thermal dependence on PCB layout and ambient conditions. At 25 °C ambient with 200 cm² copper area on a 2-layer board, each channel supports ~4.5 A continuous. Derating is required above 85 °C case temperature per Figure 33 and Table 4 - actual limit depends on R_thj-amb achieved in the final design.

Can CS1 and CS2 be connected to a single external sense resistor?

Yes, but only when CS_DIS is held high (≥2.1 V), which disables both internal current sense paths. This allows sharing of one external resistor among multiple VND5E050MJTR-E devices - however, simultaneous channel monitoring is lost, and total sensed current becomes the sum of both channels' outputs.

Does VND5E050MJTR-E support PWM dimming of LED loads?

Yes, with limitations: switching frequency must remain below 5 kHz to avoid exceeding thermal limits during repeated turn-on/turn-off cycles, and duty cycle must stay above 10% to ensure reliable current sense signal integrity. The 20 µs turn-on and 45 µs turn-off delays (Table 6) constrain minimum pulse width to ~100 µs.

How is reverse battery protection implemented?

The IC itself is not reverse-battery tolerant on V_CC or GND pins. Reverse protection requires an external network on the GND line - either a series resistor (R_GND) or Schottky diode (D_GND) as shown in Figure 29 - to limit reverse current to <200 mA (absolute max rating) and prevent latch-up or junction damage.
