Product details

Overview

VN920PEP-E from STMicroelectronics is a single-channel high-side driver IC designed for automotive and industrial load switching, featuring 15 mΩ R_DS(on), 30 A continuous output current, 36 V operating supply voltage, and integrated proportional current sense. It drives grounded loads in engine control units, body electronics, and lighting systems with protection against short circuits, overtemperature, undervoltage, overvoltage, and reverse battery conditions.

For engineers reviewing the VN920PEP-E datasheet, VN920PEP-E pinout, VN920PEP-E application, or VN920PEP-E equivalent, key selection considerations include its PowerSSO-24 thermal performance (R_thj-case = 1.3 °C/W), CMOS-compatible input logic, analog current sense ratio (K₁ = 3300–6000 A/A), and ISO 7637-2 transient immunity up to Pulse 5A.

Technical Context

The VN920PEP-E integrates VIPower™ M0-3 technology to combine power MOSFET switching with intelligent protection logic. Its active V_CC clamp limits transients to ≤55 V, while thermal shutdown triggers at 150–200 °C with 15 °C hysteresis and automatic restart. The device uses internal current limiting (30–75 A depending on temperature) rather than fixed foldback.

Current sensing is implemented via an analog I_SENSE output delivering a current proportional to load current (I_OUT/I_SENSE = 3300–6000), calibrated across -40 to +150 °C with ±10% drift. Protection states-including undervoltage (V_USD = 3–5.5 V), overvoltage (V_OV = 36 V), and loss-of-ground detection-are reported through status behavior in the truth table and sense output voltage shifts (e.g., V_SENSEH = 5.5 V during overtemperature).

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	15 mΩ at I_OUT = 10 A, T_j = 25 °C - enables low conduction loss and <1 W dissipation at 30 A
I_OUT Continuous	30 A - rated for sustained automotive solenoid, relay, and lamp loads without external heatsinking
V_CC Operating Range	5.5–36 V - supports 12 V and 24 V vehicle electrical systems including cold-crank (5.5 V) and load-dump (36 V)
Current Sense Ratio K₁	3300–6000 A/A at I_OUT = 1 A - provides scalable analog feedback for precise load monitoring and diagnostics
Thermal Shutdown Threshold	150–200 °C - protects against latch-up during overload; reset occurs at 135 °C with 15 °C hysteresis
ISO 7637-2 Pulse 5A Immunity	+86.5 V, 400 ms, 2 Ω - withstands automotive load-dump transients without external clamping
Standby Supply Current	10 µA at V_CC = 13 V - minimizes battery drain in always-on vehicle modules

Pinout & Package

Package: PowerSSO-24 - thermally enhanced exposed-pad SO package with 24 terminals, optimized for PCB copper area (R_thj-amb = 40 °C/W with 8 cm² Cu) and high-power automotive mounting.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Power supply input	Clamped to ≤55 V internally; accepts 5.5–36 V DC with active overvoltage shutdown at 36 V
GND	Ground reference	Loss-of-ground detection disables output; reverse battery protection requires external RGND/DGND network
INPUT	Digital control input	CMOS-compatible (V_IL ≤ 1.25 V, V_IH ≥ 3.25 V); includes 0.5 V hysteresis and ±6.8 V clamp
OUTPUT	High-side switched output	Drives load between OUTPUT and GND; features dV/dt control (0.1–0.9 V/ms) and demagnetization clamp
CURRENT SENSE	Analog diagnostic output	Delivers I_SENSE = I_OUT/K; shifts to 5.5 V during overtemperature for fault indication

Key Features

Feature	Design Value
Proportional current sense	Three-point calibrated ratio (K₁, K₂, K₃) across 1–30 A with ±6–10% drift over -40 to +150 °C
Integrated overvoltage clamp	Active V_CC clamp limits transients to 41–55 V, eliminating need for external TVS in ISO 7637-2 Pulse 1/2/3a/3b designs
Loss-of-ground detection	Automatic output disable when GND pin disconnects - prevents uncontrolled load activation in wiring fault scenarios
Reverse battery protection support	Compatible with external RGND resistor or DGND diode networks per Figure 19, enabling safe operation with -14 V battery reversal
Thermal management with auto-restart	Shutdown at 150–200 °C with 15 °C hysteresis and controlled restart - avoids permanent latch-off during intermittent overload

Applications

Engine Control Module (ECM)

Automotive Lighting Control

Use Scenario: Driving fuel injector solenoids and ignition coils in 12 V gasoline engines under wide ambient (-40 to +125 °C) and transient (load dump, cold crank) conditions.

IC Role / Device Role / Timing Role: High-side switch providing precise ON/OFF timing and real-time current feedback for closed-loop injector control and fault detection.

Use Value: 15 mΩ R_DS(on) reduces power loss by >40% vs. typical 25 mΩ alternatives, enabling smaller PCB layout and higher channel density in ECM modules.

Use Scenario: Controlling LED headlamps and matrix lighting arrays requiring PWM dimming, short-circuit protection, and thermal derating in compact headlamp housings.

IC Role / Device Role / Timing Role: Robust high-side driver with programmable current sense scaling and fast turn-off (50 µs delay) for accurate PWM duty cycle execution.

Use Value: Integrated overvoltage clamp (≤55 V) eliminates external TVS diodes, reducing BOM count and PCB area by 25% in space-constrained lighting modules.

Body Control Module (BCM)

Industrial Actuator Control

Use Scenario: Switching door locks, window lift motors, and HVAC blower fans in 12/24 V vehicle architectures with ESD and load-dump immunity requirements.

IC Role / Device Role / Timing Role: Fault-tolerant high-side driver with undervoltage lockout (3–5.5 V), reverse-battery network compatibility, and diagnostic current sense.

Use Value: Standby current of 10 µA extends battery life in parked vehicles; loss-of-ground detection prevents unintended actuation during wiring harness faults.

Use Scenario: Driving industrial solenoid valves and contactors in factory automation systems exposed to 24 V DC supply noise and inductive kickback.

IC Role / Device Role / Timing Role: Protected high-side switch with 30 A continuous rating, 462 mJ demagnetization energy handling, and thermal shutdown for unattended operation.

Use Value: PowerSSO-24 package delivers R_thj-case = 1.3 °C/W - enables 30 A operation without external heatsink in DIN-rail mounted PLC I/O modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Lower current rating (2.8 A), integrated gate driver only - no current sense or protection logic	Targeted at stepper motor phases, not high-power DC loads	Select only for low-current, non-diagnostic motor control where external protection is added
TLE7231EM	Similar 30 A rating and PowerSSO-36 package, but lacks proportional current sense - only digital enable/status pins	Used in cost-sensitive BCMs where analog diagnostics are omitted	Choose when system-level current monitoring is handled externally or not required

Compared with VN920PEP-E, STSPIN250 offers no integrated protection or sensing and is unsuitable for direct replacement in load-switching roles, while TLE7231EM provides comparable robustness but forfeits analog current feedback needed for predictive diagnostics and closed-loop control.

FAQ

What is the maximum safe operating temperature for VN920PEP-E?

The VN920PEP-E features thermal shutdown triggered between 150 °C and 200 °C, with automatic restart at 135 °C. Its junction temperature is internally limited, and the PowerSSO-24 package achieves R_thj-case = 1.3 °C/W. For continuous 30 A operation, PCB copper area must be ≥8 cm² to maintain case temperature ≤150 °C per Table 4 and Figure 22.

Does VN920PEP-E require external components for reverse battery protection?

Yes - reverse battery protection requires an external network: either a ground-line resistor (RGND ≤ 600 mV / I_S(on)max) or a small-signal diode (DGND) with parallel 1 kΩ resistor for inductive loads, as shown in Figure 19. The IC itself is reverse-battery tolerant only at the V_CC pin (−0.3 V), not across OUTPUT–GND.

How does the current sense output behave during fault conditions?

Under normal operation, I_SENSE = I_OUT/K (K = 3300–6000). During overtemperature, V_SENSE rises to 5.5 V (V_SENSEH). During undervoltage, overvoltage, or short-to-GND, I_SENSE drops to 0 A. These distinct analog signatures enable software-based fault classification without additional GPIOs.

Can VN920PEP-E drive inductive loads without external flyback diodes?

No - while the device includes an internal V_demag clamp (V_CC − 41 to V_CC − 55 V) for turn-off energy, it does not replace external freewheeling diodes for sustained inductive energy dissipation. External diodes remain mandatory per Figure 19 and Section 3.2 to prevent voltage overshoot beyond clamp limits during high-energy demagnetization.
