Product details
Overview
VND5T035AKTR-E from STMicroelectronics is a dual-channel high-side driver IC with integrated analog current sense, designed for 24 V automotive power distribution. It delivers 35 mΩ on-state resistance per channel, 42 A typical current limitation, and operates across 8–36 V supply range. Used in body control modules to drive resistive, inductive, or capacitive loads such as solenoids, lamps, and valves.
For engineers reviewing the VND5T035AKTR-E datasheet, VND5T035AKTR-E pinout, VND5T035AKTR-E application, or VND5T035AKTR-E equivalent, key selection criteria include AEC-Q100 qualification, fault-reset standby (FR_Stby) control logic, proportional current sense accuracy over temperature, thermal latch-off behavior, and PowerSSO-24 package thermal performance under pulsed load conditions.
Technical Context
This device implements VIPower M0-7 technology with active clamp protection, undervoltage shutdown at 5 V (0.5 V hysteresis), and self-limiting thermal transients via dynamic power limitation. Each channel features independent overload detection, short-to-VCC sensing, and off-state openload reporting through dedicated CS pins.
The analog current sense provides three calibrated gain ranges (K1/K2/K3) with ±15% ratio drift over −40 °C to +150 °C, enabling precise load monitoring from 0.2 A to 12 A. Fault reset requires a low pulse on FR_Stby, while sustained low on all inputs and FR_Stby forces standby mode with 2 µA supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 8–36 V DC - supports full automotive battery range including cold-crank (8 V) and load-dump (36 V) |
| RON (per channel) | 35 mΩ typ. at 3 A, 25 °C - enables <100 mV drop at 3 A, minimizing power loss and heat generation |
| ILIM | 42 A typ. - limits peak fault current to protect MOSFET and wiring during short-circuit events |
| Current Sense Ratio (K2) | 2930 typ. (IOUT/ISENSE) at 3 A - delivers ~1 mA sense current per 3 A load, compatible with standard ADC inputs |
| treset | 2–24 µs - defines minimum FR_Stby pulse width required to recover from thermal or overload latch-off |
| ESD Rating (HBM) | 4000 V on IN/FR_Stby pins - meets automotive robustness requirements for control-line ESD immunity |
| RthJC | 2 °C/W (one channel ON) - enables direct heatsink mounting via exposed PowerSSO-24 tab (VCC-connected) |
Pinout & Package
Package: PowerSSO-24 - thermally enhanced 24-pin exposed-tab surface-mount package with VCC connected to the thermal pad (TAB = VCC). Designed for high-power dissipation in constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Connects to vehicle battery (8–36 V); also ties to exposed thermal tab for junction-to-case heat transfer |
| GND | Power ground reference | System return path; must be low-impedance to support accurate current sense and fault detection |
| OUT1 / OUT2 | High-side power outputs | Switches load between VCC and load; each drives one side of resistive/inductive/capacitive load grounded at other end |
| IN1 / IN2 | CMOS-compatible control inputs | 3.0 V logic threshold with 0.25 V hysteresis; controls channel ON/OFF state independently |
| CS1 / CS2 | Analog current sense outputs | Deliver proportional current (ISENSE) for real-time load monitoring and fault diagnostics |
| FR_Stby | Fault reset & standby enable | Low pulse resets latch-off; sustained low with IN1/IN2 low forces ultra-low-power standby (2 µA) |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel high-side switching | Independent IN/CS/FR_Stby per channel enables asymmetric load control and diagnostics in compact BOM |
| Proportional current sense with multi-range calibration | K1/K2/K3 ratios optimized for 1 A, 3 A, and 12 A load bands - ensures <±10% sense error across full operating range |
| Comprehensive fault reporting | Single CS pin reports overload, short-to-VCC, openload (off-state), and thermal shutdown via voltage/current thresholds |
| AEC-Q100 Grade 0 qualification | Rated for −40 °C to +150 °C junction temperature - validated for engine bay and under-hood applications |
| Integrated VCC clamp and UVLO | 58 V transient clamp + 5 V undervoltage lockout with hysteresis prevents erratic operation during battery transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Single-channel, 160 mΩ RON, no analog current sense - uses digital SPI diagnostics instead | Lacks proportional current reporting; suited for binary on/off loads where sensing is handled externally | Select when system already includes ADC infrastructure and prioritizes channel count over per-channel diagnostics |
| VND7140AJTR-E | Lower current limit (14 A), higher RON (140 mΩ), same PowerSSO-24 package and FR_Stby interface | Better suited for low-power lighting or sensors; cannot sustain >20 A continuous loads like VND5T035AKTR-E | Choose for cost-sensitive designs where peak load current stays below 15 A and thermal margin is less critical |
Compared with TPS4H160-Q1 and VND7140AJTR-E, the VND5T035AKTR-E uniquely combines dual-channel operation, 35 mΩ conduction loss, and calibrated analog current sense - making it optimal for space-constrained automotive modules requiring both power efficiency and embedded diagnostics without external components.

FAQ
What is the maximum safe operating temperature for VND5T035AKTR-E?
The junction operating temperature range is −40 °C to +150 °C, with thermal shutdown triggered at 150–200 °C (typ. 175 °C). The device latches off above TTSD and resets only after junction cools to TR (≈135–140 °C), confirmed in Table 8 and Figure 12 of DS7266 Rev 6.
How does the current sense pin behave during overload conditions?
During overload, short-to-ground, or thermal shutdown, the CS pin outputs VSENSEH (7.5–9.5 V) or ISENSEH (4.9–12 mA) depending on external resistor value - signaling fault status without requiring additional comparators or logic, per Table 9 and Figure 12.
Can VND5T035AKTR-E drive inductive loads without external flyback diodes?
No external flyback diode is needed: the device integrates active demagnetization clamping (VDEMAG = VCC − 58 V to VCC − 70 V) and handles up to 250 mJ switching energy (L = 2.3 mH, VBAT = 32 V), specified in Table 3 and Section 4 of DS7266 Rev 6.
Is the PowerSSO-24 package lead-free and RoHS compliant?
Yes - the device complies with European Directive 2002/95/EC (RoHS), and the PowerSSO-24 package uses lead-free matte tin plating, verified in the "General" section of the datasheet and ST's official product change notices.
