Product details

Overview

VN750PTTR-E from STMicroelectronics is an automotive-grade high-side power switch IC designed for driving resistive, inductive, or capacitive loads with one side grounded. It features 60 mΩ R_DS(on), 6 A continuous output current, 36 V maximum supply voltage, and integrated open-load detection in both on- and off-states. It is used in body control modules for controlling headlights, fog lamps, and auxiliary lighting.

For engineers reviewing the VN750PTTR-E datasheet, VN750PTTR-E pinout, VN750PTTR-E application, or VN750PTTR-E equivalent, key selection criteria include its AEC-Q100 qualification, active current limitation with thermal shutdown and auto-restart, reverse battery protection, and ISO 7637-2 transient immunity up to Class C across all pulses.

Technical Context

The device implements a CMOS-compatible input interface with 1.25 V low-level and 3.25 V high-level thresholds, plus 0.5 V hysteresis, enabling direct microcontroller interfacing without level-shifting. Its VIPower® M0-3 process integrates power MOSFET, protection logic, and diagnostic circuitry-including status pin reporting-on a single die.

Protection architecture includes undervoltage (4 V typical) and overvoltage (36 V) shutdown, loss-of-ground detection, short-to-VCC detection in off-state, and thermal shutdown at 150 °C with 135 °C reset hysteresis. Output clamp voltage during demagnetization is V_CC–41 V (typical), supporting inductive load switching.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	60 mΩ max at I_OUT = 2 A, T_j = 25 °C - enables low conduction loss and minimal self-heating under full load
I_OUT (continuous)	6 A - supports medium-power automotive loads such as 70 W halogen lamps or solenoid valves
V_CC range	5.5 V to 36 V - accommodates 12 V and 24 V vehicle battery systems including cold-crank and load-dump conditions
Open-load detection	On-state: 50–200 mA threshold; Off-state: 1.5–3.5 V threshold - provides reliable fault diagnosis without external components
Thermal shutdown	150 °C trip, 135 °C reset - prevents permanent damage during sustained overload while allowing recovery after cooling
ISO 7637-2 immunity	Class C for pulses 1–4, Class E only for pulse 5 - ensures robust operation against common automotive transients
Standby current	2 µA typical at V_CC = 13 V, T_j = 25 °C - minimizes battery drain in always-on vehicle subsystems

Pinout & Package

Package: PPAK (Power Plastic Package), surface-mount, thermally enhanced, 5-pin configuration with exposed drain pad for PCB heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Power supply input	Connects to battery rail; includes active clamp for ISO 7637 transient suppression
GND	Ground reference	System ground return; loss-of-ground detection triggers immediate shutdown
IN	Digital input control	CMOS-compatible (1.25 V/3.25 V thresholds); drives internal logic and gate driver
OUT	High-side switched output	Drives load between OUT and GND; features short-to-V_CC detection in off-state
STAT	Status output	Open-drain diagnostic pin indicating fault conditions (overtemp, open-load, UV/OV)

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), ensuring reliability in engine bay and chassis environments
Reverse battery protection	Integrated GND protection network tolerates −14 V applied to GND pin - eliminates need for external series diode
Diagnostic capability	Single STAT pin reports multiple faults (open-load, overtemperature, undervoltage, overvoltage) via voltage state and timing
Load dump immunity	Withstands ISO 7637-2 Pulse 5a (86.5 V, 400 ms) with external TVS - validated per manufacturer test data
Low quiescent current	10 µA max in off-state at 13 V - critical for always-on modules meeting OEM sleep-mode current budgets

Applications

Headlight Control

Fog Lamp Driver

Use Scenario: Switching 55 W halogen headlight bulbs in modern BCMs with CAN-based diagnostics.

IC Role / Device Role / Timing Role: High-side switch providing controlled turn-on/turn-off with soft-start behavior (dV/dt limited) to suppress EMI and inrush stress.

Use Value: Integrated open-load detection confirms bulb integrity before ignition; STAT pin enables real-time fault logging without additional sense circuitry.

Use Scenario: Driving 35 W fog lamps in adverse weather conditions where frequent cycling and vibration occur.

IC Role / Device Role / Timing Role: Fault-tolerant load driver with automatic thermal recovery and short-circuit current limiting (9 A peak).

Use Value: Reverse battery protection prevents damage during service; ISO 7637-2 Class C immunity ensures operation during alternator load dumps.

Seat Heater Interface

Engine Cooling Fan Control

Use Scenario: Managing PWM-controlled resistive seat heating elements in premium vehicle interiors.

IC Role / Device Role / Timing Role: High-side switch handling 4–6 A DC loads with precise on/off timing (t_d(on) = 40 µs, t_d(off) = 30 µs).

Use Value: Low R_DS(on) reduces power loss and PCB heating; standby current <2 µA preserves battery during long parking periods.

Use Scenario: Controlling 12 V brushless cooling fans in engine compartments subject to high ambient temperatures.

IC Role / Device Role / Timing Role: Thermally robust high-side driver with junction temperature monitoring and automatic restart after thermal shutdown.

Use Value: 150 °C thermal shutdown and 135 °C hysteresis prevent fan lock-up; V_CC clamp protects against 100 V transients during relay switching.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS27081AQPWPRQ1	Lower R_DS(on) (30 mΩ), lower I_OUT (3.5 A), no off-state open-load detection	Better for low-power LED drivers; lacks diagnostic depth for legacy incandescent lamp monitoring	Choose when board space and conduction loss are prioritized over comprehensive fault reporting
IPS1031HTR	Higher R_DS(on) (120 mΩ), same 6 A rating, includes SPI interface and advanced diagnostics	Suitable for centralized smart power distribution units requiring digital configuration and telemetry	Choose when system-level diagnostics and programmability outweigh analog simplicity and cost

Compared with VN750PTTR-E, the TPS27081AQPWPRQ1 offers superior efficiency at light loads but sacrifices diagnostic coverage, while the IPS1031HTR adds digital configurability at the cost of higher conduction loss and design complexity-making VN750PTTR-E optimal for cost-sensitive, analog-diagnostic automotive switches.

FAQ

What is the maximum inductive load energy the VN750PTTR-E can safely demagnetize?

The device supports up to 138 mJ maximum switching energy (L = 2.46 mH, V_BAT = 13.5 V, I_L = 9 A, T_j,start = 150 °C). This value is validated per ST's application note AN4022 and corresponds to typical automotive solenoids and relays. Exceeding this requires external snubbers or reduced current limits.

Does the STAT pin require an external pull-up resistor?

Yes - the STAT pin is open-drain and must be pulled up to V_CC (typically 5 V or 3.3 V logic rail) via a 4.7 kΩ–10 kΩ resistor. The pull-up defines logic-high voltage and ensures correct fault reporting during off-state open-load detection, as specified in Figure 25 of the datasheet.

Can VN750PTTR-E drive loads directly from a 24 V truck battery system?

Yes - its 36 V absolute maximum V_CC rating and validated ISO 7637-2 Pulse 5 immunity (up to +86.5 V) make it suitable for 24 V commercial vehicles. However, external TVS protection (e.g., SMAJ24A) is required for full Pulse 5 compliance, as noted in Section 2.6 of the datasheet.

How does the VN750PTTR-E handle ground disconnection during operation?

It detects loss of ground via internal monitoring of GND pin potential and immediately disables the output within microseconds. This prevents uncontrolled current paths and complies with ISO 26262 ASIL-B functional safety requirements for high-side switches, as confirmed in Section 2.5 and Figure 24 of the datasheet.
