Product details

Overview

VN920-E from STMicroelectronics is a single-channel high-side driver IC designed for automotive and industrial load switching, featuring 16 mΩ R_DS(on), 30 A continuous output current, 36 V max V_CC, CMOS-compatible input, and proportional analog current sense (K ≈ 4400 A/A). It drives grounded loads in engine control units, body electronics, and lighting modules with integrated short-circuit, overvoltage, undervoltage, thermal, and loss-of-ground protection.

For engineers reviewing the VN920-E datasheet, VN920-E pinout, VN920-E application, or VN920-E equivalent, key selection criteria include its 1.3 °C/W junction-to-case thermal resistance, ±10% current sense ratio drift over temperature, ISO 7637-2 transient immunity (Class C up to Pulse 4), and PENTAWATT vertical package compatibility with high-power PCB layouts.

Technical Context

The VN920-E integrates VIPower™ M0-3 BCD technology to combine power DMOS output stage with smart protection logic and analog current sensing. Its active V_CC clamp (41–55 V) and demag clamp (V_CC − 41 V) suppress low-energy transients per ISO 7637-2. The device implements dual-stage current limitation: fast 75 A peak short-circuit limit (T_j = 25°C) and thermal shutdown at 150–200°C with 135°C reset hysteresis.

Current sense output delivers I_SENSE = I_OUT/K (K = 3300–6000 A/A depending on I_OUT and T_j) with 500 µs delay to 90% response and <10 µA leakage. Input logic features 0.5 V hysteresis, 3.25 V VIH, and internal clamping (−0.7 V / +6.8 V), enabling direct MCU interface without external level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	16 mΩ @ I_OUT = 10 A, T_j = 25°C - enables <1.6 W conduction loss at 30 A, reducing heatsink requirements
I_OUT Continuous	30 A - supports high-current solenoids, fuel pumps, and headlamp drivers without external current sharing
V_CC Range	5.5–36 V - covers full automotive battery range including cold-crank (5.5 V) and load-dump (36 V)
Current Sense Ratio K	4400 A/A typ. @ I_OUT = 10 A - delivers ~2.27 mA I_SENSE per 10 A load for accurate shuntless monitoring
Thermal Shutdown	150°C trip, 135°C reset - provides safe automatic recovery after overload without system latch-up
ISO 7637-2 Immunity	Pulse 1–5 Class C - survives automotive transients including load dump (Pulse 5: +86.5 V, 400 ms) without damage or functional interruption
Standby Current	10 µA max @ V_CC = 13 V - meets automotive low-power sleep mode requirements (e.g., CAN wake-up systems)

Pinout & Package

The VN920-E is housed in a PENTAWATT vertical package (ECOPACK®), featuring 5 leads with exposed thermal pad for enhanced heat dissipation. Lead pitch is 2.54 mm; case height is 10.4 mm; thermal resistance junction-to-case is 1.3 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Power supply input	Accepts 5.5–36 V DC; includes active clamp (41–55 V) and reverse-battery protection via external GND network
GND	Ground reference	Device substrate and sense reference; loss-of-ground detection triggers automatic shutdown
INPUT	Digital control input	CMOS-compatible (VIH = 3.25 V, VIL = 1.25 V); 0.5 V hysteresis prevents noise-induced switching
OUTPUT	High-side switched output	Drives load between OUTPUT and ground; integrates V_DS limiter and demag clamp (V_CC − 41 V)
CSENSE	Analog current sense output	Sinks proportional current (I_SENSE = I_OUT/K); 400 Ω output impedance enables direct ADC interface

Key Features

Feature	Design Value
Proportional current sense	4400 A/A typical gain with ±10% drift over −40°C to +150°C - eliminates need for external shunt resistor and associated power loss
Loss-of-ground detection	Automatic shutdown when GND pin disconnects - prevents uncontrolled load activation in wiring fault conditions
Reverse battery protection	Supported via external RGND resistor or DGND diode network (per Figure 19) - avoids damage during service battery reversal
Short-circuit current limit	75 A peak @ T_j = 25°C, self-adjusting with temperature - sustains brief overloads while preventing bond-wire fusing
Low standby power	10 µA max supply current - enables always-on applications (e.g., door module wake-up circuits) without battery drain

Applications

Engine Control Unit (ECU)

Automotive Body Control Module (BCM)

IC Role / Device Role / Timing Role: High-side switch with precise current feedback for closed-loop injector timing and diagnostics.

Use Value: Enables real-time coil current monitoring (via CSENSE) to detect open/short faults within 500 µs, improving OBD-II compliance.

Use Scenario: Controlling power windows, seat motors, and HVAC blowers in centralized BCMs.

IC Role / Device Role / Timing Role: Robust load driver with integrated thermal and short-circuit protection for intermittent high-torque loads.

Use Value: Eliminates need for discrete fuses and relays; automatic restart after thermal shutdown maintains user experience during sustained motor stall.

LED Headlamp Driver

Industrial PLC Output Stage

Use Scenario: Switching high-intensity LED arrays in adaptive front-lighting systems (AFS).

IC Role / Device Role / Timing Role: Constant-current-capable high-side driver with analog sense for luminance regulation and thermal derating.

Use Value: Delivers stable 30 A drive with <16 mΩ R_DS(on), minimizing voltage drop across LED string and enabling PWM dimming down to 100 Hz.

Use Scenario: Replacing electromechanical relays in DIN-rail mounted programmable logic controllers for factory automation.

Use Value: Provides digital status (via CSENSE) and fault logging (overtemp/short) without auxiliary sensors, reducing BOM count by 3+ components per channel.

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	Integrated gate driver + MOSFET; 2.8 A max I_OUT; no analog current sense	Targeted at low-power BLDC motor control, not high-current resistive/inductive loads	Select when space-constrained PCBs require integrated FET and need only basic enable/disable control
TPS27081A	36 V, 8.5 A, 20 mΩ; no thermal shutdown or current sense; smaller SOIC-8 package	Lacks protection features required for automotive under-hood environments	Choose for cost-sensitive industrial power distribution where transient immunity and diagnostics are secondary

Compared with VN920-E, STSPIN250 offers integration but sacrifices current capacity and diagnostics, while TPS27081A trades robustness and sensing for compactness and lower cost-neither matches the VN920-E's combination of 30 A drive, analog sense, and full automotive-grade protection.

FAQ

What is the maximum allowable V_CC transient voltage the VN920-E can withstand?

The VN920-E features an active V_CC clamp rated 41–55 V (typical 48 V) and complies with ISO 7637-2 Pulse 5 (load dump) up to +86.5 V for 400 ms. Its internal clamp activates before reaching absolute maximum rating (41 V DC), limiting energy dissipation and preventing damage during validated automotive transients.

How does the current sense output behave during thermal shutdown?

During thermal shutdown (T_j ≥ 150°C), the VN920-E forces CSENSE to output V_SENSEH = 5.5 V (with 400 Ω impedance), providing a clear diagnostic flag to the MCU. This overrides normal proportional scaling and persists until junction temperature falls below 135°C reset threshold.

Can the VN920-E drive inductive loads without external flyback diodes?

No. While the VN920-E includes a V_CC clamp and demag clamp (V_CC − 41 V), it lacks an integrated flyback path. External freewheeling diodes (D_ld) must be placed across inductive loads per Figure 19 to suppress voltage spikes exceeding V_CC + 41 V during turn-off.

What is the recommended external resistor for reverse battery protection using the RGND method?

For single-device use, RGND ≤ 600 mV / I_S(on)max (e.g., ≤20 Ω for 30 A). Power dissipation must be calculated as P_D = (−V_CC)² / R_GND. ST recommends Solution 2 (DGND diode + 1 kΩ parallel resistor) for multi-driver systems to avoid input threshold shifts and simplify thermal design.
