Product details
Overview
VN7000AYTR from STMicroelectronics is a single-channel automotive smart high-side driver in PowerSSO-36 package, designed for 12 V grounded loads with 3 V/5 V CMOS-compatible control. It delivers 1.3 mΩ on-state resistance (low Rmode), 200 A current limitation, and operates down to 3 V during cold cranking. Used in power distribution modules for engine control units and body electronics.
For engineers reviewing the VN7000AYTR datasheet, VN7000AYTR pinout, VN7000AYTR application, or VN7000AYTR equivalent, key selection criteria include cranking voltage margin (3 V min), MultiSense analog feedback resolution, Rmode-selectable RDS(on), latch-off thermal shutdown behavior, and AEC-Q100 qualification for under-hood deployment.
Technical Context
This device implements VIPower® M0-7 technology to integrate power MOSFET, gate driver, protection logic, and multiplexed analog diagnostics in one die. Its dual RDS(on) modes (1.3 mΩ low / 4.2 mΩ high) enable trade-offs between conduction loss and current-sense precision across load ranges.
The MultiSense architecture uses a single analog output pin (MultiSense) to sequentially deliver proportional signals for load current (K3 = 25,000 A/A typ), chip temperature (−5.5 mV/K), and VCC supply (VSENSE_VCC = VCC/8), controlled by SEL0/SEL1 and enabled by SEn. Fault reporting includes short-to-VCC, OFF-state open-load (2–4 V threshold), and dynamic ΔTJ_SD-based latch-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance (RON_L) | 1.3 mΩ at 30 A, 25°C - enables <1 W conduction loss at 100 A, critical for high-current power distribution. |
| Current limit (ILIMH) | 200 A typ - provides robust short-circuit protection for solenoids, fuel pumps, and HVAC actuators without external fusing. |
| Min cranking voltage (VUSD_Cranking) | 3 V - ensures reliable operation during deep cold cranking per LV124 Rev 2013, supporting −40°C engine starts. |
| Standby current (ISTBY) | 20 µA max at 125°C - minimizes battery drain in always-on vehicle domains like alarm systems and telematics. |
| MultiSense accuracy (dK3/K3) | ±8% over temperature - supports closed-loop current monitoring for adaptive load control in ECU-level diagnostics. |
| Thermal shutdown (TTSD) | 150–175°C - latches off output until fault reset via INPUT toggle, preventing thermal runaway in confined enclosures. |
| ESD rating (INPUT) | 4000 V HBM - withstands handling and assembly stress without damage, reducing field failure risk. |
Pinout & Package
Package: PowerSSO-36 - thermally enhanced exposed-tab surface-mount package with integrated heatsink capability (Rthj-case = 1.4 °C/W), optimized for high-power automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Accepts 4–28 V DC; clamped to 40 V transient; reverse-battery protected via internal self-switching PowerMOS. |
| OUTPUT | High-side power output | Drives grounded loads; features integrated clamp diode (VDEMAG = VCC − 41 V) for inductive kickback suppression. |
| GND | Power ground reference | Low-impedance return path; loss-of-ground detection triggers fault state and disables output. |
| INPUT | CMOS-compatible control input | Hysteresis-enabled (0.2 V); toggles output state and unlatches fault condition after thermal shutdown. |
| MultiSense | Multiplexed analog diagnostic output | Delivers current-proportional (25 kA/A), temperature-proportional (−5.5 mV/K), or VCC/8 signals; requires external 1 kΩ sense resistor. |
| SEn | Sense enable control | Active-high; disables MultiSense during low-power sleep to reduce system quiescent current. |
| SEL0, SEL1 | Multiplexer address inputs | Select diagnostic mode: 00 = current, 01 = chip temperature, 11 = VCC; all CMOS-compatible (3 V/5 V). |
| R_mode | RDS(on) operating mode select | High = 4.2 mΩ (higher current sense gain); Low = 1.3 mΩ (lower conduction loss); adapts to load requirements. |
Key Features
| Feature | Design Value |
|---|---|
| MultiSense analog feedback | Single-pin multiplexed sensing of load current, VCC, and TCHIP with ±8% full-scale accuracy - eliminates need for discrete sense resistors and ADC channels. |
| Rmode-selectable RDS(on) | Switches between 1.3 mΩ (low-loss) and 4.2 mΩ (high-sensitivity) modes - optimizes efficiency vs. diagnostic resolution per load profile. |
| Deep-cranking operation | Functional down to 3 V supply with no latch-up - meets LV124 Rev 2013 requirements for start-stop and cold-climate vehicles. |
| Latch-off thermal protection | ΔTJ_SD-triggered shutdown with manual reset via INPUT toggle - prevents uncontrolled reactivation during overheating events. |
| Reverse battery immunity | Self-switching PowerMOS blocks −16 V reverse supply without external components - reduces BOM count and layout area. |
Applications
| Engine Start/Stop Control | Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INFINEON BTS7008-1EPP | Higher RDS(on) (2.5 mΩ), no multiplexed analog feedback - uses separate pins for current sense and temperature. | Lacks integrated VCC monitoring and multi-mode RDS(on) selection; requires external op-amps for current scaling. | Choose when board space allows discrete sensing and lower cost outweighs diagnostic integration. |
| NXP MC33883A | Lower current limit (120 A), no cranking support below 4.5 V, and no Rmode flexibility - fixed 3.5 mΩ RDS(on). | Not qualified to LV124; unsuitable for deep-cold environments; limited to cabin-grade ambient temperatures. | Prefer only for non-critical interior loads where cranking margin and extended temperature range are not required. |
Compared with VN7000AYTR, BTS7008-1EPP trades diagnostic integration for cost and BTS7008-1EPP offers higher thermal robustness but lacks cranking headroom; MC33883A simplifies design at the expense of AEC-Q100 cold-cranking compliance and MultiSense versatility.

FAQ
What is the purpose of the R_mode pin?
The R_mode pin selects between two on-resistance operating modes: low R_mode sets RDS(on) to 1.3 mΩ for minimal conduction loss in high-current loads, while high R_mode increases it to 4.2 mΩ to improve current-sense gain and accuracy for lower-current diagnostics. This adaptability allows one device to serve diverse load profiles without redesign.
How does MultiSense provide three different measurements on one pin?
MultiSense uses internal analog multiplexing controlled by SEL0 and SEL1 logic inputs: SEL0=0/SEL1=0 selects load current (IOUT/ISENSE = 25,000 A/A), SEL0=0/SEL1=1 selects chip temperature (−5.5 mV/K), and SEL0=1/SEL1=1 selects VCC (VSENSE = VCC/8). SEn must be high to enable any mode, and settling times range from 20–720 µs depending on transition type.
Can VN7000AYTR survive reverse battery connection?
Yes - VN7000AYTR integrates reverse-battery protection via a self-switching PowerMOS that blocks up to −16 V applied to VCC while sinking only 200 mA reverse current. Unlike external diode solutions, this feature requires no additional components and maintains full diagnostic functionality during reverse polarity events.
What triggers latch-off thermal shutdown and how is it cleared?
Latch-off occurs when junction temperature exceeds TTSD (150–175°C) or dynamic ΔTJ_SD threshold (60 K), disabling OUTPUT until a fault reset sequence is executed: toggle INPUT from high to low and back to high while SEn remains asserted. This prevents automatic recovery during unsafe thermal conditions and ensures operator or ECU intervention.
