Product details

Overview

VN750B5-E from STMicroelectronics is a monolithic high-side power switch IC designed in VIPower® M0-3 technology for driving grounded loads in automotive and industrial applications. It features 60 mΩ R_DS(on), 6 A continuous output current, 36 V maximum supply voltage, on/off-state open-load detection, and integrated short-circuit, overvoltage, undervoltage, thermal, and reverse-battery protection.

For engineers reviewing the VN750B5-E datasheet, VN750B5-E pinout, VN750B5-E application, or VN750B5-E equivalent, this device is selected for robust load control in 12 V/24 V battery systems where diagnostic feedback, fault resilience, and AEC-Q100 compliance are required.

Technical Context

The VN750B5-E implements a CMOS-compatible input stage with hysteresis (0.5 V), enabling direct interfacing with microcontroller I/Os. Its status pin provides real-time diagnostics including overload, overtemperature (TTSD = 150–200 °C), and open-load conditions via active-low logic-level output.

Protection architecture includes active V_CC clamping compliant with ISO 7637-2 pulses (Class C up to Pulse 4), current limiting (6–15 A depending on V_CC), and automatic thermal shutdown with 135 °C reset hysteresis. Output demagnetization clamp voltage is V_CC−41 V to V_CC−55 V under inductive turn-off.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	60 mΩ max at I_OUT = 2 A, T_j = 25 °C - ensures low conduction loss and <1 W dissipation at 6 A in typical automotive ambient
I_OUT (continuous)	6 A - supports solenoids, relays, lamps, and small motors without external heatsinking in P2PAK package
V_CC range	5.5–36 V - compatible with 12 V and 24 V vehicle batteries including cold-crank (5.5 V) and load-dump (36 V) transients
Open-load detection	On-state: 50–200 mA threshold; Off-state: 1.5–3.5 V threshold - enables reliable fault reporting without external sensing components
Thermal shutdown	150–200 °C trip, 135 °C reset - prevents permanent damage during sustained overload while allowing safe auto-recovery
ISO 7637-2 compliance	Pulses 1–4 Class C, Pulse 5 Class E - meets automotive EMC requirements for battery line transients in passenger vehicles
Standby current	2 µA typical at V_CC = 13 V - minimizes parasitic drain on vehicle battery during sleep mode

Pinout & Package

The VN750B5-E is housed in a P2PAK (Power Package) surface-mount package with exposed thermal pad, optimized for high-power dissipation in compact automotive PCB layouts.

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	Must be low-impedance connection; device shuts down if disconnected (loss-of-ground protection)
IN	Digital input control	CMOS-compatible (V_IL ≤ 1.25 V, V_IH ≥ 3.25 V); 0.5 V hysteresis prevents noise-induced switching
OUT	High-side switched output	Drives load between OUT and GND; supports inductive loads with V_demag clamp
STAT	Status output	Active-low open-drain signal indicating fault conditions (overload, open-load, overtemp, UV/OV)

Key Features

Feature	Design Value
Automotive Grade	AEC-Q100 qualified - validated for operation from −40 °C to +150 °C junction temperature in harsh vehicle environments
Diagnostic capability	Integrated STAT pin reports open-load (on/off), short-to-V_CC, overcurrent, overtemperature, and supply faults - eliminates need for external monitoring circuitry
Reverse battery protection	Internal GND protection network withstands −14 V reverse polarity without external diode - reduces BOM count and PCB area
Low quiescent current	2 µA standby current - critical for always-on modules (e.g., body control units) to meet ISO 16750-2 battery drain limits
Robust transient immunity	V_CC pin clamps ISO 7637-2 Pulse 1, 2a, 2b, 3a/b, and 4 transients to safe levels - ensures reliable operation during cranking and alternator load dump

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VN750PT-E	PPAK package (smaller footprint, lower R_thj-amb = 37 °C/W on 6 cm² Cu), identical electrical specs	Better thermal performance in space-constrained modules; requires different PCB layout and reflow profile	Select for compact designs needing higher power density and improved thermal margin.
TPS4H160-Q1	TI device: 160 mΩ R_DS(on), 4 A, integrated current sense, SPI interface, no open-load off-state detection	Offers digital diagnostics but lacks off-state open-load detection and has higher on-resistance	Select when digital communication and current measurement are prioritized over analog simplicity and ultra-low R_DS(on).

Compared with VN750PT-E, the VN750B5-E offers identical protection and drive capability in a larger P2PAK package better suited for manual assembly and higher peak power handling; versus TPS4H160-Q1, it delivers lower conduction loss and simpler analog interface at the cost of programmability and current-sense integration.

FAQ

What is the maximum inductive load energy the VN750B5-E can safely demagnetize?

The VN750B5-E supports up to 138 mJ maximum switching energy (L = 2.46 mH, R_L = 0 Ω, V_bat = 13.5 V, T_jstart = 150 °C, I_L = 9 A). This value is validated per ST's test conditions and defines the upper limit for safe turn-off of inductive loads without exceeding junction temperature limits or triggering overvoltage shutdown.

Does the VN750B5-E require an external pull-up resistor on the STAT pin?

Yes - the STAT pin is an open-drain output and must be pulled up externally (typically 4.7 kΩ to V_CC) to generate a valid logic-high signal during normal operation. Without this pull-up, the STAT pin remains floating and cannot indicate "no fault" condition reliably.

Can the VN750B5-E drive loads directly from a 24 V truck battery without additional protection?

Yes - the device supports V_CC up to 36 V and includes active clamping compliant with ISO 7637-2 Pulse 5 (up to +86.5 V for 400 ms), making it suitable for 24 V commercial vehicle systems. However, external TVS or RC filtering may still be recommended for extreme ESD or long-duration transients beyond spec limits.

How does the VN750B5-E detect open-load in the off-state?

During off-state, the device applies a small internal current source to the OUT pin and monitors voltage. If V_OUT rises above 1.5–3.5 V (V_OL threshold), the STAT pin asserts low to indicate open-load. This works only when IN = low and load is disconnected from ground - confirmed by Figure 25 and Table 5 parameter VOL in the datasheet.
