Product details

Overview

VN820-B513TR from STMicroelectronics is a high-side driver IC designed for automotive and industrial load switching, featuring 40 mΩ R_DS(on), 9 A continuous output current, 36 V max supply voltage, and integrated open-load detection in both on/off states. It operates in P2PAK package and is used in body control modules to drive solenoids, lamps, and actuators with robust protection.

For engineers reviewing the VN820-B513TR datasheet, VN820-B513TR pinout, VN820-B513TR application, or VN820-B513TR equivalent, this page delivers verified electrical specs, thermal behavior under ISO 7637-2 transients, status pin logic interpretation, and real-world design guidance for reverse-battery and ground-loss protection.

Technical Context

The device implements VIPower M0-3 technology with active V_CC clamping for ISO 7637-2 pulse compatibility (Level IV), combined current limiting (9–20 A) and thermal shutdown with 150°C trip and 135°C reset hysteresis. It detects open loads via status pin using external pull-up in off state and internal threshold (1.5–3.5 V) in on state.

Protection architecture includes undervoltage lockout (4 V typ), overvoltage shutdown (36 V), reverse battery tolerance via external network, and loss-of-ground detection that forces automatic turn-off. Output demagnetization clamp limits V_OUT to V_CC−41 V during inductive turn-off.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	40 mΩ at I_OUT = 3 A, T_j = 25°C - enables low conduction loss and <1 W dissipation at 9 A in typical PCB layout
I_OUT Continuous	9 A - supports automotive solenoid and lamp loads without external heatsink under 51.9°C/W ambient thermal resistance
V_CC Range	5.5–36 V - covers 12 V and 24 V vehicle battery systems including cold-crank and load-dump conditions
Open-Load Detection	On-state: 70–300 mA threshold; Off-state: 1.5–3.5 V threshold with external pull-up - enables diagnostics without additional sensors
Thermal Shutdown	150°C trip, 135°C reset (15°C hysteresis) - prevents latch-up during sustained overload and allows safe auto-recovery
ISO 7637-2 Pulse Immunity	Level IV compliant (−100 V/100 ms, +86.5 V/400 ms) - meets automotive EMC requirements without external TVS on V_CC
Status Pin Logic	Active-low open-drain output with 0.5 V max low-level voltage at 1.6 mA - interfaces directly with 3.3 V/5 V microcontrollers

Pinout & Package

P2PAK package: 11-pin thermally enhanced surface-mount power package with exposed drain pad for low R_thj-case (1.9°C/W).

Pin/Terminal	Circuit Role	Design Meaning
1,2,3,4,5,6,7,8,9,11	OUTPUT	Power output terminals paralleled internally - share current path to reduce IR drop and thermal stress
10	GND	Ground reference for logic and power sections - must be connected before V_CC to prevent latch-up
INPUT	CMOS-compatible control input	Accepts 1.25 V low / 3.25 V high thresholds with 0.5 V hysteresis - immune to noise in harsh automotive environments
STATUS	Diagnostic open-drain output	Indicates fault conditions (open load, overtemp, UV/OV) - requires external pull-up for proper logic level translation
V_CC	Supply input	Internally clamped to 41 V - absorbs low-energy transients per ISO 7637-2 without external suppression

Key Features

Feature	Design Value
ON/OFF state open-load detection	Enables full-cycle diagnostics without external circuitry - reduces BOM count and improves system reliability
Reverse battery protection support	Compatible with external diode (DGND) or resistor (RGND ≤ 600 mV/I_S(on)max) networks - eliminates need for costly external MOSFET solutions
Loss-of-ground detection	Automatic output disable when GND pin disconnects - prevents uncontrolled load activation and ensures functional safety
Very low standby current	≤10 µA at V_CC = 13 V - meets automotive quiescent current requirements for always-on modules
Output short-to-V_CC detection	Identified in OFF state only - distinguishes wiring faults from normal operation, enabling precise fault isolation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN820SP13TR	PowerSO-10™ package (R_thj-amb = 51.9°C/W), identical electrical specs	Better thermal performance on small PCBs; not suitable for high-vibration environments due to leaded package	Select when board space is constrained and mechanical shock is minimal
INFINEON BTS724G	Lower R_DS(on) (20 mΩ), no off-state open-load detection, different status logic (active-high)	Lacks off-state diagnostics; requires external pull-down for status interface	Choose when lowest conduction loss is critical and diagnostic depth is secondary

Compared with VN820-B513TR, the STVN820SP13TR offers lower thermal resistance but reduced mechanical ruggedness, while the BTS724G trades diagnostic capability for lower on-resistance - making VN820-B513TR optimal for cost-sensitive, safety-critical automotive body electronics requiring full-cycle fault coverage.

FAQ

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

For reliable off-state open-load detection, use R_PU ≤ (V_PU − V_OLmax)/I_L(off2), where V_OLmax = 3.5 V and I_L(off2) = −75 µA (min). With V_PU = 5 V, R_PU ≤ 20 kΩ. ST recommends 10 kΩ to ensure margin against process variation and temperature drift while avoiding excessive standby current.

How does the VN820-B513TR handle reverse battery conditions?

VN820-B513TR does not tolerate reverse battery directly. ST specifies two protection methods: (1) a series ground resistor (R_GND ≤ 600 mV/I_S(on)max) or (2) a Schottky diode (D_GND) in the ground path with parallel 1 kΩ resistor for inductive loads. Both methods shift input thresholds by up to 600 mV if MCU ground is isolated.

Can the STATUS pin drive an LED directly without a buffer?

No. The STATUS pin is an open-drain output rated for 1.6 mA sink current with 0.5 V max low-level voltage. Driving an LED requires a series current-limiting resistor (e.g., 2.2 kΩ for 5 V supply) and assumes the LED anode connects to V_CC. Direct connection without current limiting risks exceeding I_STAT absolute maximum rating of ±10 mA.

What is the maximum inductive load energy the VN820-B513TR can safely demagnetize?

At T_jstart = 150°C and V_CC = 13.5 V, the maximum single-pulse switching energy is 438–526 mJ depending on inductance (3.7–4.48 mH). This corresponds to safe turn-off of a 13 A inductive load with L ≤ 4.48 mH. Exceeding this requires external freewheeling diodes or snubbers to avoid V_demag overshoot beyond V_CC−41 V.
