STMicroelectronics VND810MSP

Overview

VND810MSP from STMicroelectronics is a dual-channel high-side driver IC designed for automotive and industrial load switching, featuring 150 mΩ R_DS(on) per channel, 0.6 A continuous output current, 36 V supply voltage rating, CMOS-compatible inputs, and open-drain status outputs with on/off-state open-load detection. It protects against shorted loads, undervoltage/overvoltage, loss of ground, and reverse battery conditions-common in 12 V vehicle lighting and body control modules.

For engineers reviewing the VND810MSP datasheet, VND810MSP pinout, VND810MSP application, or VND810MSP equivalent, key selection considerations include its integrated thermal shutdown with 150 °C trip point, active current limitation calibrated to detect 21 W / 12 V bulbs as overload faults, and ISO 7637-2 transient immunity up to ±100 V (Pulse 2a/3b).

Technical Context

The VND810MSP integrates two independent VIPower M0-3 high-voltage DMOS channels in a single PowerSO-10 package, each with dedicated input, output, and status pins. Its architecture includes internal VCC clamping for low-energy transients, programmable hysteresis on logic inputs (0.5 V), and dual-mode open-load detection: current-based during on-state and voltage-threshold-based (1.5–3.5 V) during off-state.

Protection logic is fully autonomous: overtemperature shutdown triggers at 150 °C with 15 °C hysteresis; undervoltage lockout activates below 4 V typical; overvoltage shutdown engages above 36 V; and loss-of-ground detection forces automatic channel disable when GND disconnect is sensed. All protections generate diagnostic feedback via open-drain status pins.

FAQ

What is the maximum safe operating temperature for VND810MSP?

The VND810MSP has an internally limited junction operating temperature with thermal shutdown triggered at 150 °C (typical) and reset at 135 °C. Its PowerSO-10 package achieves 37 °C/W thermal resistance to ambient when mounted on 6 cm² of 35 µm copper, allowing sustained 0.6 A operation at +85 °C ambient with proper PCB layout-verified per Table 4 and Figure 28 of the datasheet.

Does VND810MSP require external components for basic operation?

Yes-external pull-up resistors (typically 10 kΩ) on STATUS1 and STATUS2 pins are mandatory to interpret diagnostic states, and a 100 nF ceramic capacitor must be placed between V_CC and GND near the device. For reverse battery protection, either a series resistor (RGND) or Schottky diode (DGND) in the ground path is required per Figure 24; no other passive components are needed for core switching functionality.

How does off-state open-load detection work without loading the output?

The VND810MSP applies a small internal test current (~50 µA) to the output during off-state and measures resulting voltage. If the output is open, voltage rises above 1.5 V (min) and triggers STATUS pin assertion; if shorted to V_CC, voltage remains near V_CC and no fault is reported. This method avoids drawing significant current from downstream loads while detecting both open and V_CC-short faults-detailed in Table 11 and Figure 25.

Can VND810MSP drive inductive loads like relays or solenoids?

Yes-it is qualified for inductive switching with demagnetization energy handling up to 225 mJ (L = 400 mH, V_BAT = 13.5 V, I_L = 0.9 A) and features an internal V_DEMAG clamp (V_CC − 41 V to V_CC − 55 V) to suppress flyback spikes. However, for loads exceeding 6 mH inductance, external freewheeling diodes are recommended to ensure reliable turn-off per Figure 26 and Section 3.5.
