STMicroelectronics VND830ASP13TR

Overview

VND830ASP13TR from STMicroelectronics is a dual-channel high-side solid-state relay IC built on VIPower M0-3 technology, designed for driving grounded loads in automotive and industrial power distribution systems. It delivers 6 A DC per channel, features 60 mΩ R_DS(on) at 25°C, integrated proportional current sense (K = 1000–2000), and comprehensive protection including thermal shutdown (T_TSD = 150°C), overvoltage clamp (41–55 V), undervoltage lockout (4 V typ), reverse battery protection, and loss-of-ground detection.

For engineers reviewing the VND830ASP13TR datasheet, VND830ASP13TR pinout, VND830ASP13TR application, or VND830ASP13TR equivalent, this device supports precise load monitoring via analog current sense outputs, robust ISO 7637-1 transient immunity (Pulse 1–5 Class C), and high-side switching with CMOS-compatible inputs - critical for body control modules, smart junction boxes, and 12 V/24 V vehicle subsystems.

Technical Context

The VND830ASP13TR integrates two independent high-side power switches with dedicated analog current sense outputs (I_SENSE1, I_SENSE2) where output current is linearly proportional to load current via programmable gain (K₁ = 1000–1900 at 0.25 A). Each channel implements autonomous protection logic: thermal shutdown triggers at 150°C with 135°C hysteresis, overvoltage shutdown activates at 36 V, and undervoltage shutdown occurs below 4 V.

It employs active V_CC clamping to suppress low-energy transients (ISO 7637-1 Pulse 1, 2, 3a/b, 4, 5), includes reverse battery protection via internal circuitry, and detects open-ground faults by disabling outputs when GND is disconnected. Switching performance includes 30 µs turn-on/off delay and controlled dV/dt (200–600 V/ms) to reduce EMI in inductive load environments.

FAQ

What is the maximum continuous output current per channel?

The VND830ASP13TR supports 6 A DC per channel under specified thermal conditions (T_C ≤ 150°C, R_thj-case = 1.2°C/W). At 2 A and 25°C junction temperature, R_DS(on) is 60 mΩ; it rises to 120 mΩ at 150°C. Derating is required above 100°C case temperature per Figure 11 in the datasheet.

How does the current sense function work, and what external components are needed?

The current sense outputs (pins 9 and 10) deliver I_SENSE = I_OUT/K, where K ranges from 1000 to 2000 depending on load and temperature. A pull-up resistor (typically 3.9 kΩ to V_CC) converts I_SENSE to a measurable voltage. No op-amp or ADC is required for basic monitoring, though precision measurement benefits from low-impedance routing and filtering.

Does the device meet automotive transient standards without external components?

Yes - the VND830ASP13TR passes ISO 7637-1 Pulse 1 through 5 at Class C levels with only the recommended application schematic (page 8 of datasheet), thanks to its integrated V_CC clamp, reverse battery protection, and internal current limiting. No external TVS diode is required for Pulse 1, 2, 3a/b, or 4; Pulse 5 compliance depends on board layout and heatsinking.

Can unused input or sense pins be left floating?

No - unused INPUT pins may be left unconnected, but unused CURRENT SENSE pins must be tied to GND to prevent noise coupling and ensure stable biasing of internal sense circuitry. Leaving sense pins floating can cause erroneous current readings or increased leakage current per Section 4.3 of the datasheet.
