Product details

Overview

VN820-11-E from STMicroelectronics is an automotive-grade high-side driver IC in PENTAWATT package, designed for ground-referenced resistive/inductive loads with 40 mΩ R_DS(on), 9 A continuous output current, and 36 V V_CC rating. It integrates on/off-state open-load detection, thermal shutdown with diagnosis, undervoltage/overvoltage protection, and reverse battery protection - used in body control modules for headlight, fog light, and HVAC blower switching.

For engineers reviewing the VN820-11-E datasheet, VN820-11-E pinout, VN820-11-E application, or VN820-11-E equivalent, key selection criteria include its AEC-Q100 qualification, CMOS-compatible input logic, active current limitation (9–20 A), status pin diagnostic capability, and robust transient immunity per ISO 7637-2 Pulse 1/2/3a/3b/5.

Technical Context

The VN820-11-E implements a VIPower® M0-3 monolithic high-side switch with integrated protection logic: thermal shutdown triggers at 150–200 °C with 135 °C reset and 7–15 °C hysteresis; undervoltage lockout activates below 3–5.5 V with 0.5 V hysteresis; overvoltage clamp limits V_CC to 36 V. Its status pin provides open-drain fault reporting with 0.5 V low-level output at 1.6 mA sink.

It supports load dump immunity per ISO 7637-2 Pulse 5 (+26.5 V / +46.5 V), electrostatic discharge tolerance up to 5 kV on V_CC/output, and detects off-state short-to-V_CC via VOL threshold (1.5–3.5 V) and on-state open-load via I_OL threshold (70–300 mA) with 200 µs detection delay.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	40 mΩ typical at 3 A, 25 °C - enables low conduction loss and <1 W dissipation at 9 A in optimized PCB layout
I_OUT continuous	9 A - supports high-power automotive loads like cooling fans and solenoids without external heatsink under 51.9 °C/W R_thj-amb
V_CC range	5.5–36 V - compatible with 12 V and 24 V vehicle electrical systems including cold-crank (5.5 V) and load dump (36 V clamp)
Open-load detection	On-state: 70–300 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 - protects against sustained overload while allowing automatic recovery after cooldown
Status pin	Open-drain, 0.5 V max low-level at 1.6 mA - directly interfaces with 3.3 V/5 V MCU GPIO for real-time diagnostics
ESD rating	5 kV HBM on V_CC and output pins - exceeds automotive system-level ESD requirements without additional protection devices

Pinout & Package

PENTAWATT package: 15-pin vertical through-hole with exposed thermal pad (mechanical data per ST Doc ID 10890 Rev 8, Section 5.2). Pin 1 = Input (IN), Pin 2 = Ground (GND), Pin 3 = Output (OUT), Pin 4 = Status (STAT), Pin 5 = V_CC. Unused pins (6–15) are internally unconnected and must be left floating per Table 2 of datasheet.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	CMOS-compatible digital input	Accepts 1.25 V low / 3.25 V high logic; 0.5 V hysteresis prevents noise-induced switching
2 (GND)	Power and signal reference	Must be connected to chassis ground; disconnecting GND forces automatic shutdown per internal safety logic
3 (OUT)	High-side switched output	Drives load between OUT and ground; features active V_CC clamp and demagnetization energy handling up to 156 mJ
4 (STAT)	Diagnostic open-drain output	Pulls low during faults (overtemp, UV/OV, open-load, short-to-V_CC); requires external pull-up resistor
5 (V_CC)	Main supply input	36 V rated; includes internal clamp diode (0.6 V forward drop at 2 A, 150 °C) for load dump suppression

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 0 (−40 to +150 °C junction), ECOPACK® RoHS/lead-free - certified for engine bay and under-hood deployment
Integrated protection suite	Thermal shutdown + UV/OV lockout + output stuck-to-V_CC detection + reverse battery protection - eliminates need for discrete protection circuitry
Diagnostic status pin	Single-pin fault reporting covering 6 distinct conditions (truth table Table 12) - reduces MCU GPIO count and simplifies firmware fault handling
Low standby current	≤10 µA at V_CC = 13 V, T_j = 25 °C - meets automotive "always-on" module quiescent power budgets
Robust transient immunity	ISO 7637-2 Pulse 1 (−100 V), Pulse 2a (+100 V), Pulse 3b (+100 V), Pulse 5 (+46.5 V) - survives real-world vehicle electrical disturbances

Applications

IC Role / Device Role / Timing Role: High-side driver enabling PWM dimming and diagnostics via STAT pin; handles inrush currents up to 9 A.

Use Value: Eliminates need for external current sense and thermal monitoring; open-load detection prevents false bulb-out warnings during filament burnout.

Use Scenario: Controlling 12 V DC brushless blower motors in automotive climate control systems.

IC Role / Device Role / Timing Role: High-side power switch with fast turn-on/turn-off (30 µs delay) and demagnetization energy handling (156 mJ).

Use Value: Enables soft-start and stall detection via current limitation and STAT feedback, improving motor reliability and noise reduction.

Fog Light Activation

Seat Heater Power Management

Use Scenario: Driving dual-filament fog lights with independent low/high beam control and thermal derating.

IC Role / Device Role / Timing Role: AEC-Q100 qualified high-side switch with thermal shutdown and automatic restart - sustains intermittent high-load operation.

Use Value: Prevents thermal runaway during extended use; status pin alerts MCU to reduce duty cycle before shutdown occurs.

Use Scenario: Managing 24 V seat heater elements with precise temperature-based current limiting and open-circuit detection.

IC Role / Device Role / Timing Role: High-side driver with 9 A continuous rating and off-state short-to-V_CC detection - verifies heater integrity before activation.

Use Value: Detects broken heater wires or connector disconnection before power application, avoiding unsafe "no heat" failure mode.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VN820-E	PENTAWATT package, tube packaging, no tape-and-reel option	Same electrical specs; identical pinout and thermal performance	Select when manual assembly or low-volume prototyping is required
VN820-12-E	PENTAWATT package, tape-and-reel packaging (TR suffix not used; -12-E denotes reel variant per Table 1)	Identical functionality; optimized for automated SMT placement	Select for high-volume production with pick-and-place equipment

Compared with VN820-E and VN820-12-E, the VN820-11-E shares identical electrical behavior and thermal characteristics but is specifically designated for tube packaging - making it optimal for engineering validation, small-batch builds, and repair stocking where reel handling is impractical.

FAQ

What is the maximum continuous output current rating for VN820-11-E?

The VN820-11-E is rated for 9 A continuous output current at T_c = 25 °C with proper PCB copper area (6 cm², 35 µm thick), based on R_thj-amb = 51.9 °C/W and internal current limitation set to 9–20 A depending on V_CC. Derating applies above 25 °C case temperature per Figure 23 in the datasheet.

Does VN820-11-E support 24 V truck/bus electrical systems?

Yes - the device operates from 5.5 V to 36 V V_CC, with overvoltage clamp at 36 V and validated immunity to ISO 7637-2 Pulse 5 (+46.5 V), making it suitable for both 12 V passenger vehicles and 24 V commercial vehicle platforms without external clamping components.

How does the status pin indicate open-load faults?

The status pin pulls low for both on-state open-load (I_OUT < 70 mA) and off-state short-to-V_CC (V_OUT > 1.5 V), with 200 µs and 1000 µs detection delays respectively. The same pin also reports thermal shutdown, undervoltage, overvoltage, and output stuck conditions per Table 12 truth table.

Is VN820-11-E pin-compatible with other VN820 variants?

Yes - all VN820-E variants (including VN820SP-E, VN820B5-E, VN820PT-E, VN820-12-E, and VN820-11-E) share identical pinout, electrical characteristics, and functional behavior. Only package type (PENTAWATT vs PowerSO-10 vs P2PAK vs PPAK) and packaging format (tube vs reel) differ between part numbers.
