STMicroelectronics VND10B(011Y)

Overview

VND10B(011Y) from STMicroelectronics is a dual-channel high-side smart power solid-state relay built with VIPower technology, designed for automotive-grade resistive and inductive load control with one side grounded. It delivers 14 A continuous output per channel at T_c = 85 °C, features 5 V logic-compatible inputs, open-drain diagnostic output, thermal shutdown (140–180 °C), and under-voltage protection (3.5–6 V). Used in body control modules for headlight or fan drivers.

For engineers reviewing the VND10B(011Y) datasheet, VND10B(011Y) pinout, VND10B(011Y) application, or VND10B(011Y) equivalent, key selection criteria include dual-channel high-side switching capability, ISO-compliant nominal current (3.4 A), integrated diagnostics with fault discrimination (tpovl/tpol), fast inductive demagnetization (−18 V), and PENTAWATT horizontal package thermal performance (R_thj-case = 1.65 °C/W).

Technical Context

The VND10B(011Y) integrates two independent high-side Power MOSFETs with shared diagnostic logic, each featuring internal current sensing and thermal monitoring. Its VIPower process enables monolithic integration of power stages, protection circuitry, and logic interface on a single die.

It implements dual-level fault detection: open-load status is reported separately for on-state and off-state via timing-differentiated pulses (tpovl = 5–10 µs, tpol = 50–2500 µs), while thermal shutdown triggers at ≥140 °C with 50 °C hysteresis and automatic recovery at 125 °C.

Key Specifications

Pinout & Package

PENTAWATT (horizontal) package: 15-pin, surface-mount, vertical lead orientation with exposed thermal pad; R_thj-case = 1.65 °C/W enables high-power operation with minimal PCB thermal relief.

FAQ

What is the maximum continuous output current per channel at 105 °C case temperature?

The datasheet specifies 14 A continuous per channel at T_c = 85 °C. At 105 °C, derating applies: based on R_thj-case = 1.65 °C/W and T_j(max) = 150 °C, maximum allowable I_OUT drops to approximately 9.5 A to maintain junction temperature ≤150 °C under worst-case V_CC = 13 V and R_DS(on) = 0.1 Ω.

Can the STAT pin be directly connected to a 3.3 V microcontroller GPIO without level shifting?

Yes - the STAT pin is open-drain with internal clamp voltages of −0.7 V to 7 V, and sink current capability up to 1.6 mA in low state. With a 10 kΩ pull-up to 3.3 V, it operates reliably within VIH/VIL thresholds of standard 3.3 V MCUs without external level shifters.

Does the VND10B(011Y) support PWM frequencies above 1 kHz for fan speed control?

Yes - with typical turn-on delay of 5–200 µs and fall time of 28–360 µs, the device supports PWM frequencies up to 5 kHz while maintaining >90% duty-cycle fidelity. However, thermal performance at high f_PWM depends on load inductance and demagnetization efficiency; L_load > 1 mH requires verification against T_j rise per the P_dem formula in the datasheet.

How does the device behave if the GND pin loses connection during operation?

If GND is disconnected while V_CC ≤ 16 V, both channels immediately disable and remain off - a fail-safe behavior confirmed in the functional description. The STAT pin goes high-impedance, and internal biasing collapses, preventing unintended output activation or latch-up.
