Product details

Overview

VND7012AY-E from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-36 package, featuring MultiSense analog feedback for load current (±5% accuracy), VCC supply voltage, and chip temperature monitoring. It delivers 12 mΩ on-state resistance per channel, 75 A current limitation, and supports 3 V/5 V CMOS logic inputs. Designed for turn indicators and headlamps driving up to 3×P27W bulbs or parallel R5W lamps.

For engineers reviewing the VND7012AY-E datasheet, VND7012AY-E pinout, VND7012AY-E application, or VND7012AY-E equivalent, key selection criteria include diagnostic multiplexing capability, latch-off configurability via FaultRST, reverse-battery protection, ISO 7637-2 transient immunity, and off-state open-load detection - all validated for AEC-Q100 Grade 0 automotive environments.

Technical Context

The device integrates two independent VIPower® M0-7 high-side switches with active power limitation during overload and thermal shutdown with configurable latch-off. Each channel features dedicated input hysteresis (0.2 V), undervoltage lockout (4 V trip, 5 V reset), and overvoltage clamping at 41 V.

MultiSense functionality uses a single analog output pin multiplexed across three diagnostics: proportional load current sense (1:2000 mirror ratio), VCC monitoring (±3% full-scale), and TCHIP sensing (±5°C accuracy). Selection is controlled by SEL0/SEL1, enabled by SEn, with fault status reported via FaultRST pin behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC operating range	4–28 V DC: supports cold-crank (4 V) and load-dump (28 V) conditions in 12 V automotive systems.
R_ON (per channel)	12 mΩ typ. at 25°C: enables <1 W conduction loss at 7 A, critical for thermally constrained modules.
ILIMH current limit	75 A typ.: sustains short-circuit events without external fusing while limiting peak junction temperature rise.
ISTBY standby current	0.5 µA max. at 25°C: ensures negligible battery drain during vehicle sleep mode.
MultiSense accuracy	±5% load current, ±3% VCC, ±5°C TCHIP: enables precise closed-loop diagnostics without external ADCs.
Transient immunity	ISO 7637-2 Pulse 5b clamped to 40 V (RL = 4 Ω): meets OEM-level surge robustness requirements.
FaultRST function	Active-low pin: unlatches outputs after thermal/power faults or enables auto-restart mode when held low.

Pinout & Package

Package: PowerSSO-36 - thermally enhanced exposed-pad SOIC variant with 36-pin layout optimized for high-current automotive PCB mounting and thermal dissipation (R_thj-board = 4 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail connection; supports 4–28 V operation and clamps transients to 41 V.
OUTPUT0, OUTPUT1	High-side switched outputs	Drive grounded loads; each rated for 75 A peak with integrated current limitation and thermal foldback.
GND	Power ground reference	Low-inductance return path; includes reverse-battery protection via self-turn-on diode structure.
INPUT0, INPUT1	CMOS-compatible control inputs	Accept 3 V/5 V logic; feature 0.2 V hysteresis to reject noise in harsh automotive environments.
MultiSense	Multiplexed analog diagnostic output	Delivers proportional current representing load current, VCC, or chip temperature based on SEL0/SEL1 state.
SEn	Sense enable control	Active-high signal enabling MultiSense output; allows disabling diagnostics during low-power module sleep.
SEL0, SEL1	Multiplexer address inputs	Select diagnostic source: 00 = load current, 01 = VCC, 10 = TCHIP, 11 = reserved.
FaultRST	Fault reset / latch control	Active-low pin: resets latched fault condition or configures auto-restart behavior when held low.

Key Features

Feature	Design Value
Dual-channel high-side switching	Independent control of two 12 V automotive loads with shared diagnostics and protections.
MultiSense analog feedback	Single-pin multiplexed sensing of load current, supply voltage, and die temperature - eliminating need for discrete sensors.
Configurable fault latch-off	FaultRST pin determines whether thermal or power-limit faults remain latched or auto-recover.
Reverse-battery protection	Self-turn-on MOSFET structure prevents damage during -16 V reverse connection without external components.
Off-state open-load detection	Monitors output voltage in OFF state to identify broken filament or disconnected lamp - critical for turn-signal compliance.
ISO 7637-2 compliant immunity	Validated against Pulse 1, 2a, 2b, 3a, 3b, and 5b - meets stringent OEM EMC requirements for body electronics.

IC Role / Device Role / Timing Role: Smart power switch with integrated diagnostics, protecting MCU I/Os and reducing BOM count.

Use Value: Reduces system-level fault diagnosis time by >90% through direct analog feedback instead of polling discrete sensors.

Use Scenario: Driving seat heater elements and mirror adjustment motors with short-circuit and overtemperature protection.

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 R_ON, no analog current sense - uses digital SPI diagnostics only.	Lacks MultiSense analog multiplexing; requires external ADC for current/voltage/temperature monitoring.	Preferred when SPI-based diagnostics and lower channel count suffice; not suitable for legacy analog-sensor interfaces.
VND7050AJTR-E	Single-channel, 50 mΩ R_ON, same MultiSense architecture but no FaultRST latch configuration - fixed auto-restart.	Cannot hold outputs latched after fault; unsuitable where manual reset or fail-safe hold is required.	Used where simplified fault handling is acceptable and higher R_ON is tolerable for lower-current loads.

Compared with TPS4H160-Q1 and VND7050AJTR-E, the VND7012AY-E uniquely combines dual-channel integration, ultra-low R_ON, analog multiplexed diagnostics, and user-configurable fault latch behavior - making it optimal for cost-sensitive, space-constrained BCMs requiring full analog diagnostic compatibility.

FAQ

What is the maximum continuous output current per channel?

The VND7012AY-E does not specify a continuous current rating due to thermal dependency on PCB layout and ambient conditions. Its 75 A current limitation is a peak short-circuit threshold. Continuous current must be determined from thermal data: with R_thj-board = 4 °C/W and T_jmax = 150°C, sustained 10 A operation is feasible on a 4-layer board with adequate copper area, assuming 13 V VCC and 25°C ambient.

How does the MultiSense pin distinguish between load current, VCC, and chip temperature?

MultiSense output is digitally multiplexed using SEL0 and SEL1 pins: 00 selects proportional load current (1:2000 mirror), 01 selects VCC feedback (scaled to 0–20 mA), and 10 selects TCHIP (linear 10 µA/°C). The SEn pin must be high to enable any mode. No internal ADC is used - all signals are analog current outputs calibrated across temperature.

Can the FaultRST pin be left unconnected?

No. FaultRST is an active-low input with internal pull-up; leaving it floating risks unintended fault unlatching or erratic latch behavior. ST recommends connecting it to MCU GPIO with 10 kΩ pull-up if not actively driven, or directly to GND for permanent auto-restart mode. Table 2 specifies "Through 15 kΩ resistor to GND" for unused configurations.

Is reverse-battery protection implemented without external components?

Yes. The VND7012AY-E integrates a self-turn-on protection structure that conducts during reverse-battery events (down to –16 V), safely shunting current away from sensitive circuitry. This eliminates the need for external Schottky diodes or MOSFETs typically required in conventional high-side drivers, reducing BOM cost and PCB footprint.
