Product details

Overview

VN16B(011Y) from STMicroelectronics is a high-side smart power solid-state relay IC designed for automotive ISO-compliant load switching, featuring 20 A continuous output current at Tc = 85 °C, 40 V drain-source breakdown voltage, 0.06 Ω on-state resistance, and integrated open-drain diagnostic output. It drives grounded resistive or inductive loads in engine control modules, body electronics, and lighting systems.

For engineers reviewing the VN16B(011Y) datasheet, VN16B(011Y) pinout, VN16B(011Y) application, or VN16B(011Y) equivalent, key selection criteria include thermal shutdown threshold (140–180 °C), inductive demagnetization clamp (–18 V), under-voltage lockout (3.5–6 V), and ISO-defined nominal current (5.6 A at V_DS ≤ 0.5 V).

Technical Context

The VN16B(011Y) integrates a VIPower MOSFET with embedded protection logic, using junction-temperature sensing for thermal shutdown at ≥140 °C and automatic recovery at 125 °C. Its diagnostic output discriminates fault types via delay timing: t_povl = 5–10 µs for overtemperature and t_pol = 50–2500 µs for open-load detection.

It implements fast inductive demagnetization via internal negative clamp (–18 V typical), reducing dissipation during turn-off by controlling energy release rate. Input logic is 5 V compatible with internal 6 V clamp, and undervoltage protection triggers between 3.5 V and 6 V to prevent erratic operation during battery sag.

Key Specifications

STAT	Open-drain diagnostic output	Signals open load (on/off), short-to-V_CC, or overtemperature via voltage level and timing

Key Features

Feature	Design Value
ISO-compliant high-side switching	Meets automotive ISO 7637-2 and ISO 16750-2 requirements for load driving and fault tolerance
Integrated thermal protection	Self-resetting shutdown at 140–180 °C with 15–50 °C hysteresis prevents latch-up during overload
Inductive load demagnetization	–18 V clamp enables controlled flyback energy release, reducing stress on MOSFET and EMI
Multi-fault diagnostic output	Single STAT pin distinguishes open load, overtemperature, and short-to-V_CC via timing and logic state
Low standby power	25–50 µA quiescent supply current minimizes battery drain in sleep-mode vehicle systems

Applications

Engine Control Unit (ECU)

Automotive Lighting System

Use Scenario: Driving fuel injectors and ignition coils in 12 V automotive powertrain systems.

IC Role / Device Role / Timing Role: High-side switch providing precise current-controlled actuation with fast demagnetization.

Use Value: –18 V demagnetization clamp reduces coil turn-off time and eliminates need for external snubbers.

Use Scenario: Controlling headlamp, fog lamp, and daytime running light (DRL) modules.

IC Role / Device Role / Timing Role: ISO-compliant high-side driver with diagnostic feedback for functional safety compliance.

Use Value: Open-load detection (via STAT timing) enables real-time bulb-out reporting to vehicle CAN network.

Body Control Module (BCM)

Heating/Ventilation Actuators

Use Scenario: Managing power windows, door locks, and seat motor actuators in centralized body electronics.

IC Role / Device Role / Timing Role: Protected high-side switch with thermal foldback and short-circuit immunity.

Use Value: 20 A continuous rating supports peak stall currents of brushed DC motors without external fusing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN16BTR	Tape-and-reel packaging; identical electrical specs and pinout	No difference - same device, alternate packaging format for automated assembly	Select for SMT production lines requiring reel-fed placement
IPS1021H	Lower I_OUT (12 A), higher R_on (0.12 Ω), integrated current sense	Lacks –18 V demagnetization; adds analog current monitoring output	Prefer when real-time load current feedback is required over fast inductive turn-off

Compared with VN16B(011Y), STVN16BTR offers identical performance in tape-and-reel form for volume manufacturing, while IPS1021H trades demagnetization capability for current-sensing functionality-making it suitable for closed-loop motor control but not for high-dI/dt inductive loads like fuel injectors.

FAQ

What is the function of the STAT pin on VN16B(011Y)?

The STAT pin is an open-drain diagnostic output that signals fault conditions: low during overtemperature or open-load-on, high during normal operation or open-load-off. Delay timing (t_povl vs. t_pol) allows microcontroller firmware to distinguish fault types without additional hardware.

Can VN16B(011Y) drive inductive loads without external components?

Yes-it integrates fast demagnetization with a –18 V clamp, eliminating the need for external freewheeling diodes or snubbers. However, reverse-battery protection requires an external Schottky diode between GND and chassis ground per Figure 10 in the datasheet.

What is the minimum supply voltage required for reliable operation?

VN16B(011Y) requires V_CC ≥ 6 V for guaranteed turn-on and full functionality. Undervoltage lockout activates between 3.5 V and 6 V, disabling output to prevent undefined behavior during cranking or brownout conditions.

How does thermal shutdown reset after activation?

Thermal shutdown is self-resetting: the device turns off at ≥140 °C and automatically resumes operation once junction temperature falls to ≤125 °C. Hysteresis (15–50 °C) prevents oscillation near the trip point during sustained marginal overload.
