STMicroelectronics VND10BSP13TR

Overview

VND10BSP from STMicroelectronics is a dual-channel ISO-compliant high-side smart power solid-state relay designed for automotive and industrial load switching with grounded-load topology. It delivers 3.4 A nominal output current per channel at V_CC = 13 V, features 0.1 Ω on-state resistance, 40 V drain-source breakdown voltage, and integrated open-load/over-temperature diagnostics. It drives resistive or inductive loads in body control modules and lighting systems.

For engineers reviewing the VND10BSP datasheet, VND10BSP pinout, VND10BSP application, or VND10BSP equivalent, key selection criteria include thermal shutdown threshold (140–180 °C), diagnostic delay differentiation (tpovl = 5–10 µs vs. tpol = 50–2500 µs), inductive demagnetization capability (V_demag ≈ −18 V), and reverse-battery protection compatibility via external Schottky diode.

Technical Context

The VND10BSP integrates two independent high-side power switches with shared diagnostic output, each using vertical intelligent power MOSFET technology. It implements ISO 7637-compliant transient immunity, under-voltage lockout (V_USD = 3.5–6 V), and fast inductive demagnetization (−18 V clamp) to limit energy dissipation during turn-off.

Its diagnostic logic discriminates fault types by timing: open-load-on (tpol) and overtemperature (tpovl) generate distinct status pulse delays. Thermal protection activates at T_j ≥ 140 °C and resets at 125 °C, with hysteresis of 50 °C. Input is 5 V logic-compatible with 0.2–1.5 V hysteresis and internal 6 V clamp.

FAQ

What is the maximum continuous output current per channel at T_c = 105 °C?

At T_c = 105 °C, the VND10BSP supports 11.2 A per channel (derated from 14 A at 85 °C using linear interpolation per thermal data sheet). This assumes proper PCB copper area (minimum recommended pad size on FR-4) and ambient airflow consistent with R_thj-amb = 60 °C/W.

Can the STAT pin drive an LED directly without a current-limiting resistor?

No. The STAT pin is open-drain with V_STAT(L) = 0.4 V at I_STAT = 1.6 mA. Driving an LED requires an external pull-up resistor (e.g., 4.7 kΩ to 5 V) and series current-limiting resistor (e.g., 330 Ω) to ensure I_STAT stays within ±10 mA absolute maximum rating.

Does the VND10BSP support PWM switching at frequencies above 1 kHz?

Yes. With typical rise/fall times of 28–360 µs and turn-on/turn-off delays of 5–500 µs, the VND10BSP supports PWM up to ~500 Hz for full on/off control. For higher-frequency modulation (e.g., 20 kHz audio dimming), use constant-current mode with external feedback rather than direct PWM on IN pins.

How does the device behave during reverse-battery connection without external protection?

Without external Schottky diode protection, reverse-battery voltage exceeding −4 V applied to V_CC will damage the device. The absolute maximum rating specifies −4 V reverse supply voltage; operation below this threshold is not guaranteed and may cause latch-up or permanent failure.
