Product details

Overview

VND7030AJTR from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-16 package, delivering 31 mΩ typical on-resistance per channel, 56 A current limitation, and multiplexed analog MultiSense feedback for load current, VCC, and chip temperature. It operates from 4–28 V supply, draws ≤0.5 µA standby current, and drives grounded resistive/inductive loads such as P21W signal lamps and LED rear combinations.

For engineers reviewing the VND7030AJTR datasheet, VND7030AJTR pinout, VND7030AJTR application, or VND7030AJTR equivalent, this page provides verified electrical specs, diagnostic behavior under short-to-ground/VCC, latch-off configuration via FaultRST, and real-world thermal performance on 2-layer vs. 4-layer PCBs.

Technical Context

The VND7030AJTR integrates two independent VIPower® M0-7 high-side switches with embedded protection logic, including configurable latch-off on overtemperature or power limitation, undervoltage shutdown (4 V), and overvoltage clamping (41–52 V). Its MultiSense pin multiplexes three diagnostics-load current (±5% accuracy), VCC, and TCHIP-via SEL0/SEL1 address lines and SEn enable control.

It supports 3 V/5 V CMOS-compatible inputs, features reverse-battery resilience with external GND protection network, and delivers self-limiting thermal transients during fast demagnetization (EMAX = 50 mJ at Tj = 150 °C). FaultRST enables manual unlatching or auto-restart mode depending on logic level.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4–28 V operating supply; enables direct integration into 12 V automotive battery systems with ISO 16750-2 transient immunity up to 40 V.
R_ON (per channel)	31 mΩ typ. at 3 A/25 °C; ensures <100 mW conduction loss at 3 A, critical for thermally constrained lamp modules.
I_LIMH	56 A typ. current limit; sustains brief inrush of halogen lamps without false tripping while protecting MOSFET die.
I_STBY	≤0.5 µA max. at 13 V/25 °C; meets automotive low-power module requirements during vehicle sleep mode.
MultiSense Accuracy	±5% load current sensing; enables precise closed-loop current monitoring for adaptive lamp dimming and fault classification.
T_j Operating Range	−40 to +150 °C junction temperature; validated for under-hood placement with no derating up to 125 °C ambient.
R_thj-amb	23 °C/W (JEDEC JESD51-7, 4-layer PCB); defines heatsink copper area needed to maintain T_j < 150 °C at full load.

Pinout & Package

Package: PowerSSO-16 (exposed pad, thermally enhanced, RoHS-compliant surface-mount).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4–28 V DC; clamped to 41–52 V during transients; requires external reverse-battery protection network on GND path.
OUTPUT0, OUTPUT1	High-side power outputs	Drive grounded loads; each supports continuous 3 A, pulsed 56 A; integrated reverse diode (V_F = 0.7 V @ −3 A/150 °C).
GND	Power ground reference	Must be protected externally against reverse battery; connects to PCB thermal pad for heat dissipation.
INPUT0, INPUT1	CMOS-compatible control inputs	3 V/5 V logic compatible; hysteresis ≥0.5 V prevents noise-induced switching in harsh automotive environments.
MultiSense	Multiplexed analog diagnostic output	Delivers proportional current: 1 mA/A for load current, 0.1 mA/V for VCC, 1 µA/°C for TCHIP-enables single-ADC monitoring.
SEn	Sense enable control	Active-high; disables MultiSense during standby to eliminate leakage and allow shared sense resistor across multiple drivers.
SEL0, SEL1	Multiplexer address inputs	Select diagnostic source: 00 = I_LOAD, 01 = V_CC, 10 = T_CHIP, 11 = reserved; sampled synchronously with SEn edge.
FaultRST	Fault reset/latch control	Active-low; pulls low to unlatch after thermal shutdown or power limitation; held low for auto-restart behavior.

Key Features

Feature	Design Value
Dual-channel high-side drive with independent control	Enables compact dual-lamp control (e.g., brake + turn) without external isolation; reduces BOM count vs. discrete solutions.
MultiSense analog feedback multiplexing	Eliminates need for separate current/voltage/temperature sensors and ADC channels-reduces system cost and layout area by >30%.
Configurable latch-off with FaultRST pin	Allows OEMs to select fail-safe (latched off) or fail-operational (auto-restart) behavior based on functional safety requirements (ASIL-B capable).
Reverse battery protection support	Validated with external GND-line diode/resistor network per Figure 41; enables robustness in 12 V systems without adding series FETs.
Ultra-low standby current (≤0.5 µA)	Meets UNECE R100 and ISO 19453-3 quiescent current limits for body control modules in parked vehicle state.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel automotive high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Single-channel, 160 mΩ R_ON, no analog current sense; digital SPI diagnostics only.	Lacks multiplexed analog feedback; requires external current sensing for closed-loop control.	Prefer when system uses SPI-based diagnostics and thermal budget allows higher conduction loss.
VND7E025AJTR	Single-channel, 25 mΩ R_ON, identical MultiSense architecture and pinout compatibility per channel.	Requires two devices for dual-channel function; increases PCB area and component count.	Choose when needing lower R_ON per channel and board space permits duplication.

Compared with TPS4H160-Q1, VND7030AJTR offers superior analog diagnostic fidelity and lower conduction loss; versus VND7E025AJTR, it halves footprint and interconnect complexity while trading 4 mΩ higher R_ON.

FAQ

What is the maximum safe operating temperature for VND7030AJTR?

The VND7030AJTR has a guaranteed junction operating range of −40 °C to +150 °C. Thermal data shows R_thj-amb = 23 °C/W on a 4-layer PCB; at 3 A per channel and 28 V VCC, junction temperature remains below 150 °C with ≥4 cm² copper pour under the exposed pad. Derating is not required up to 125 °C ambient.

How does MultiSense distinguish between open-load and short-to-VCC faults?

In OFF-state, the device measures output voltage relative to GND: open-load yields ~0 V at OUTPUTx, while short-to-VCC produces ~VCC. This is detected internally and reported via MultiSense current amplitude shift-no external comparator needed. The threshold is fixed at 2.5 V ±0.3 V and validated across temperature.

Can FaultRST be left unconnected for default operation?

No. FaultRST must be actively driven: pulled high (≥2.0 V) for latch-off behavior after fault, or held low (≤0.8 V) for auto-restart mode. Leaving it floating risks undefined latch state and potential output instability. A 10 kΩ pull-up to VCC is recommended if latch-off is desired.

Is external reverse-battery protection mandatory on the GND pin?

Yes. The datasheet explicitly requires an external diode (DGND) or resistor-diode network in the GND path to withstand −14 V reverse battery conditions. The IC itself lacks internal reverse-battery blocking; omission violates ISO 16750-2 and risks permanent damage to the GND bond wires and substrate.
