Product details
Overview
VNQ9025AJTR from STMicroelectronics is a quad-channel automotive-grade smart high-side driver in PowerSSO-16 package, designed to control 12 V grounded resistive/inductive/capacitive loads via 3 V/5 V CMOS-compatible inputs. It delivers 25 mΩ typical on-state resistance per channel, 30 A current limitation, and <0.5 µA standby current, enabling deep cold-cranking operation compliant with LV124 (2013). Used in ADAS radar/sensor power distribution and P27W lamp driving.
For engineers reviewing the VNQ9025AJTR datasheet, VNQ9025AJTR pinout, VNQ9025AJTR application, or VNQ9025AJTR equivalent, key selection criteria include its multiplexed analog current sense feedback (K = 4960 ±7% at 2.1 A), configurable latch-off fault recovery, reverse-battery protection, and AEC-Q100 qualification for under-hood automotive environments.
Technical Context
The device integrates four independent VIPower M0-9 high-side switches with embedded thermal shutdown, undervoltage lockout (2.7 V trip), overvoltage clamp (36–45 V), and load-current limiting (32.5 A typ. at -40 °C, 27 A at 150 °C). Each channel features hysteresis-enabled CMOS inputs and dedicated diagnostics including OFF-state open-load detection using external pull-up.
Its multifunction CS pin provides time-multiplexed analog current sensing across all four channels via SEL0/SEL1 address lines, with ±7% gain accuracy at full-scale 2.1 A output and sub-30 µs channel-to-channel transition delay. FaultRST enables active-low configurable latch-off reset or auto-restart mode selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 4–28 V DC - supports wide automotive battery range including cold-crank down to 4 V |
| On-state resistance (per channel) | 25 mΩ typ. at 25 °C - enables low conduction loss and <1 W dissipation at 2.1 A |
| Current limit (ILIMH) | 32.5 A typ. at -40 °C - self-limiting protection against short-circuit faults without external components |
| Standby current | 0.5 µA max. at 25 °C - minimizes parasitic drain in always-on vehicle modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Higher RON (60 mΩ), no multiplexed analog CS, uses digital SPI diagnostics instead of analog current mirror | Lacks proportional current feedback; requires external ADC or SPI host for load monitoring | Choose when digital communication and programmable fault thresholds outweigh need for analog current sensing |
| BD82001FV-M | Triple-channel only, lower current limit (15 A), no reverse-battery protection, no OFF-state open-load detection | Not suitable for P27W lamps or radar power where open-load detection is mandatory | Select only for cost-sensitive non-safety-critical 3-channel applications without cold-crank or reverse-battery requirements |
Compared with TPS4H160-Q1 and BD82001FV-M, VNQ9025AJTR uniquely combines quad-channel integration, analog multiplexed current sensing with ±7% gain accuracy, reverse-battery immunity, and deep cold-crank capability - making it optimal for ADAS and lighting systems demanding both precision diagnostics and robustness.

FAQ
What is the maximum continuous output current per channel?
The VNQ9025AJTR supports 2.1 A DC output current per channel under typical conditions (VCC = 13 V, TJ = 25 °C), with internal current limiting set to 32.5 A typ. at -40 °C. Sustained operation above 2.1 A depends on PCB thermal design and ambient temperature, as specified in the thermal data table (RthJA = 54.7 °C/W on 2-layer board).
How does the multiplexed current sense (CS) pin work across four channels?
The CS pin outputs a current proportional to the selected channel's load current (ISENSE = IOUT/K), with K = 4960 ±7% at 2.1 A. Channel selection is controlled by SEL0 and SEL1 logic inputs (00–11 binary), and SEn must be high to enable output. Transition delay between channels is ≤30 µs, and settling time after selection is ≤200 µs.
Can VNQ9025AJTR detect an open load when the output is turned off?
Yes - OFF-state open-load detection is supported using an external pull-up resistor on the OUTx pin. When INx = low and the load is disconnected, the OUTx voltage rises to >2 V (threshold: 2–4 V), triggering diagnostic reporting via the CS pin when that channel is selected and SEn is high.
What fault conditions trigger latch-off versus auto-restart behavior?
Latch-off occurs when thermal shutdown (TJ > 150–210 °C) or power limitation is detected and FaultRST is held high; output remains off until FaultRST is pulsed low. Auto-restart activates when FaultRST is held low, causing the device to cycle on/off with thermal hysteresis (reset at 135 °C) until the fault clears.
