Product details

Overview

VNHD7012AYTR from STMicroelectronics is an AEC-Q100 qualified dual-channel automotive H-bridge motor driver integrating two fully protected high-side drivers (R_DS(on) = 12 mΩ typ per channel) and gate drivers for external low-side MOSFETs, delivering 38 A continuous output current per channel with PWM operation up to 20 kHz - deployed in power seat and HVAC blower control modules.

For engineers reviewing the VNHD7012AYTR datasheet, VNHD7012AYTR pinout, VNHD7012AYTR application, or VNHD7012AYTR equivalent, this page delivers verified technical context, MultiSense analog/diagnostic mapping, thermal shutdown behavior, VDS monitoring configuration, and real-world automotive load protection implementation details.

Technical Context

The VNHD7012AYTR implements a dual-channel VIPower-based architecture with independent high-side drivers and dedicated gate drivers for external N-channel low-side MOSFETs, enabling full H-bridge operation with half-bridge flexibility. It integrates undervoltage shutdown (4 V threshold), overvoltage clamping, cross-current and shoot-through protection, and fast thermal transient limitation via active power limiting.

MultiSense functionality provides simultaneous analog monitoring of motor current, chip temperature, and battery voltage on a single pin, configurable via SEL0/SEL1 address lines; diagnostic flags include short-to-ground, short-to-VCC, open-load in OFF-state, and thermal shutdown indication - all reported through the same analog output with external resistor scaling.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Current	38 A continuous per channel - supports high-torque DC motors in automotive seating and HVAC systems without external heatsinking beyond PCB copper.
R_DS(on)	12 mΩ typical per high-side channel at T_j = 25 °C - enables <1.5 W conduction loss at 38 A, critical for thermal management in confined ECU enclosures.
V_CC Max	38 V - accommodates 24 V automotive systems with load-dump transients per ISO 7637-2 Pulse 5a (up to +35 V).
PWM Frequency	Up to 20 kHz - avoids audible noise in cabin fan and seat actuator applications while maintaining precise torque control.
Thermal Shutdown	150 °C junction temperature with latch-off - prevents die degradation during sustained overload or blocked-rotor conditions.
MultiSense Channels	Motor current, battery voltage, and chip temperature multiplexed onto one analog output - reduces MCU ADC channel count and simplifies fault reporting.
Protection Coverage	Includes short-to-battery (via V_DS monitoring), loss of ground/V_CC, ESD (±4 kV HBM), and reverse battery protection via integrated charge pump - meets ASIL-B functional safety requirements.

Pinout & Package

Package: PowerSSO-36 exposed pad - optimized for thermal dissipation in automotive under-hood and dashboard environments; R_thj-case = 2.4 °C/W per channel enables >30 W power handling with minimal board copper.

Pin/Terminal	Circuit Role	Design Meaning
OUTA / OUTB (Pins 1–10, 27–36)	High-side switch source terminals	Direct connection points to motor windings; each group forms one H-bridge leg with external low-side MOSFETs.
INA / INB (Pins 16, 21)	Direction/brake logic inputs	CMOS-compatible (3 V logic) signals that directly interface microcontroller GPIOs to select forward/reverse/brake states.
GATE_LSA / GATE_LSB (Pins 13, 24)	External low-side MOSFET gate drivers	Provide 12 V gate drive with fast rise/fall times to ensure robust switching of external N-MOSFETs in low-side position.
MultiSense (Pin 19)	Analog feedback and diagnostic output	Single-pin multiplexed output for motor current, V_BATT, and T_chip; requires external resistor network to scale voltage ranges per function.
SEL0 / SEL1 (Pins 11, 26)	MultiSense multiplexer address lines	Select which parameter (current/voltage/temp) appears on MultiSense pin - enables time-division multiplexing with standard MCU sampling.
VREF_OVL_LSA / VREF_OVL_LSB (Pins 15, 22)	V_DS monitoring reference inputs	Set short-to-battery detection thresholds for each low-side MOSFET by connecting external resistors between drain and these pins.
CP (Pin 17)	Charge pump output	Drives gate of external P-MOSFET in battery path to enable reverse polarity protection - eliminates need for series diode.

Key Features

Feature	Design Value
Dual high-side drivers with integrated protection	Each channel includes current limiting, thermal shutdown, and cross-conduction prevention - eliminates discrete protection circuitry and reduces BOM count by ≥7 components per channel.
V_DS monitoring for external LSDs	Configurable short-to-battery detection using external resistors on VREF_OVL pins - enables fail-safe shutdown before external MOSFET failure propagates to system wiring.
MultiSense analog multiplexing	Three critical parameters (motor current, battery voltage, die temperature) shared on one analog output - cuts required MCU ADC channels from 3 to 1 and simplifies PCB routing.
Standby mode with blanking time	60–550 µs t_{D_STBY} ensures glitch-free entry/exit from low-power state - prevents unintended motor activation during microcontroller wake-up sequences.
Reverse battery protection via charge pump	Integrated CP output drives external P-MOSFET to block reverse current - achieves <10 mΩ total path resistance vs. 50+ mΩ with Schottky diode solutions, reducing power loss and heat generation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel automotive H-bridge motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BD37023FV	Single-channel high-side driver (no integrated LSD gate drivers); max I_OUT = 25 A; no MultiSense analog multiplexing.	Lacks dual-channel coordination and external low-side drive - requires separate gate drivers and additional MCU resources for multi-motor systems.	Choose when only one motor needs driving and cost-per-channel is prioritized over integration density.
VN5E025AJTR-E	Single-channel protected high-side driver; 25 A rating; no V_DS monitoring or MultiSense; uses SO-8 package.	No H-bridge capability or PWM support - limited to unidirectional loads like solenoids or fans without reversal.	Select for simple ON/OFF loads where bidirectional control and diagnostics are unnecessary.

Compared with BD37023FV and VN5E025AJTR-E, the VNHD7012AYTR uniquely integrates dual high-side drivers, external low-side gate drivers, and three-parameter analog diagnostics on one pin - reducing component count by ≥40% and enabling ASIL-B-compliant motor control in space-constrained automotive ECUs.

FAQ

What is the maximum PWM frequency supported by the VNHD7012AYTR for external low-side MOSFETs?

The VNHD7012AYTR supports PWM operation up to 20 kHz for external low-side MOSFETs, as confirmed in Section 1 of the datasheet. This frequency avoids audible noise in cabin applications while maintaining sufficient resolution for torque control. Gate driver rise/fall times are optimized for 4.7 nF gate capacitance, ensuring reliable switching at full frequency without shoot-through risk.

How does the MultiSense pin provide three different measurements on a single output?

The MultiSense pin outputs voltage-scaled representations of motor current, battery voltage, and chip temperature in time-division multiplexed format. Selection is controlled by SEL0 and SEL1 pins per Table 12 in the datasheet; each combination routes a specific internal signal to the pin. External RC filtering and MCU sampling synchronization enable accurate separation of the three parameters without additional hardware.

Can the VNHD7012AYTR drive a motor in half-bridge mode only?

Yes - the VNHD7012AYTR supports half-bridge operation by configuring one high-side driver with external low-side MOSFETs while leaving the second channel unused or repurposed. The truth tables in Sections 12 and 13 confirm valid states for single-leg drive, and the device maintains full protection coverage (current limit, thermal shutdown, V_DS monitoring) even in asymmetric configurations.

What external components are required for short-to-battery protection on the low-side MOSFETs?

Short-to-battery protection requires external resistors connected between the drain of each low-side MOSFET and its corresponding VREF_OVL pin (Pin 15 for LSA, Pin 22 for LSB). The resistor values set the V_DS threshold per Equation 3 in Section 3.4; typical values range from 10 kΩ to 100 kΩ depending on desired trip point and MOSFET R_DS(on). No additional ICs or comparators are needed.
