Product details

Overview

VN820(011Y) from STMicroelectronics is a high-side driver IC designed for automotive and industrial load switching, featuring CMOS-compatible input, on/off-state open-load detection, short-circuit protection, undervoltage/overvoltage shutdown, loss-of-ground protection, 40 mΩ R_DS(on), 9 A continuous output current, and 36 V maximum supply voltage. It operates in harsh environments including ISO 7637-2 transient conditions and supports inductive loads such as solenoids and relays.

For engineers reviewing the VN820(011Y) datasheet, VN820(011Y) pinout, VN820(011Y) application, or VN820(011Y) equivalent, key selection considerations include its integrated status reporting, thermal shutdown with automatic restart, reverse battery protection capability, and compatibility with 5 V microcontroller logic levels.

Technical Context

The VN820(011Y) implements a monolithic VIPower M0-3 process high-side switch with active current limiting, thermal shutdown (trip at 150–200 °C), and dual-mode open-load detection-using internal comparators to monitor output voltage during both ON and OFF states. Its status pin provides real-time fault reporting via open-drain logic-level output.

Protection architecture includes active V_CC clamping for low-energy transients (ISO 7637 Pulse 1/2/3a/3b compliant), reverse-battery tolerance via external ground network design, and demagnetization voltage clamping (V_demag = V_CC − 41 to V_CC − 55 V) during inductive turn-off. Input hysteresis (0.5 V) ensures noise immunity in automotive wiring harnesses.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	40 mΩ max at I_OUT = 3 A, T_j = 25 °C - enables low conduction loss and minimal self-heating under full load
I_OUT Continuous	9 A - supports high-current automotive actuators without external heatsinking under typical PCB copper area
V_CC Range	5.5 V to 36 V - compatible with 12 V and 24 V vehicle electrical systems including cold-crank and load-dump conditions
Open-Load Detection	ON-state threshold: 70–300 mA; OFF-state threshold: 1.5–3.5 V - enables reliable diagnostics without external components beyond pull-up resistor
Thermal Shutdown	150–200 °C trip range with 135 °C reset and 7–15 °C hysteresis - prevents latch-up and allows safe auto-recovery after overload
Input Logic Compatibility	V_IL ≤ 1.25 V, V_IH ≥ 3.25 V, VIH hysteresis = 0.5 V - directly interfaces with standard 5 V CMOS/TTL microcontrollers
Status Pin Output	V_STAT(L) ≤ 0.5 V at I_STAT = 1.6 mA - drives LED or MCU interrupt with minimal external biasing

Pinout & Package

Package: PowerSO-10™ (vertical mounting, exposed drain pad for thermal dissipation). Thermal resistance R_thj-case = 1.9 °C/W enables 65.8 W power dissipation at T_C = 25 °C.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8, 9	OUTPUT (parallel)	High-side switched output terminals - internally paralleled for low R_DS(on) and high current handling
10	V_CC	Main supply input - includes active clamp for ISO 7637 transient suppression up to ±100 V
11	GND	Power ground reference - requires external reverse-battery protection network per application schematic
12	INPUT	CMOS-compatible control input - 1 µA leakage, 0.5 V hysteresis, 1.25 V/3.25 V logic thresholds
13	STATUS	Open-drain diagnostic output - reports faults (overtemp, open-load, overvoltage) as low-active signal

Key Features

Feature	Design Value
On/Off-State Open-Load Detection	Eliminates need for external sense resistors or ADC monitoring - reduces BOM count and improves system reliability
Integrated Short-Circuit Protection	Active current limiting (9–20 A range) combined with thermal shutdown prevents device destruction during sustained overload
Loss-of-Ground Fault Detection	Automatic turn-off when GND pin disconnects - avoids uncontrolled load activation and protects downstream circuitry
Reverse Battery Protection Support	Compatible with external diode (DGND) or resistor (RGND) ground networks - enables robust operation in 12 V automotive systems
ISO 7637-2 Transient Immunity	Passes Level IV testing (Pulse 1: −100 V, Pulse 2: +100 V, Pulse 5: +86.5 V) without external TVS - simplifies EMC design

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN820SP	Same die, PowerSO-10™ package with enhanced thermal performance (R_thj-amb = 51.9 °C/W @ 0.5 cm² Cu) and tape-and-reel packaging	Preferred for automated SMT assembly and higher-power-density layouts requiring improved thermal management	Select when volume production, reflow compatibility, or lower thermal resistance is required over tube-packaged VN820(011Y)
INFINEON BTS724G	Higher R_DS(on) (60 mΩ), lower I_OUT (7.5 A), no off-state open-load detection, different status logic polarity	Lacks diagnostic capability for disconnected loads in OFF state - requires external circuitry for full fault coverage	Choose only if legacy design reuse or specific Infineon ecosystem integration is mandated; not drop-in for diagnostic-critical applications

Compared with VN820(011Y), VN820SP offers identical functionality with optimized packaging for production, while BTS724G sacrifices diagnostic completeness and thermal margin for cost-sensitive non-safety applications.

FAQ

What is the recommended external pull-up resistor value for off-state open-load detection?

For reliable off-state open-load detection, use an external pull-up resistor (R_PU) between OUTPUT and V_PU (e.g., +5 V). R_PU must satisfy two constraints: (1) V_OUT < V_OLmin when load is connected → R_PU > (V_PU × R_L) / V_OLmin − R_L; (2) V_OUT > V_OLmax when load is disconnected → R_PU < (V_PU − V_OLmax) / I_L(off2). Typical values range from 10 kΩ to 47 kΩ depending on load impedance and supply voltage.

Does VN820(011Y) require an external flyback diode for inductive loads?

No external flyback diode is required. The VN820(011Y) integrates active demagnetization clamping with V_demag = V_CC − 41 to V_CC − 55 V, which safely dissipates inductive energy during turn-off. This feature eliminates discrete diodes for most solenoid and relay applications, reducing board area and component count.

How does the STATUS pin behave during thermal shutdown?

During thermal shutdown (T_j > T_TSD = 150–200 °C), the STATUS pin goes low and remains low until junction temperature falls below T_R = 135 °C. The delay from overtemperature event to STATUS assertion is ≤20 µs, enabling fast fault response in safety-critical systems without software polling.

Can VN820(011Y) be used in 24 V truck applications with load dump protection?

Yes - VN820(011Y) supports V_CC up to 36 V DC and passes ISO 7637-2 Pulse 5 (up to +86.5 V, 400 ms) when paired with an external load-dump suppressor (D_ld). Its internal V_CC clamp handles lower-energy transients (Pulses 1–4), but D_ld is mandatory for full load-dump immunity in 24 V commercial vehicle systems.
