STMicroelectronics VNQ05XSP1613TR

Overview

VNQ05XSP1613TR from STMicroelectronics is a quad-channel high-side solid-state relay IC designed for automotive and industrial load switching with ground-referenced loads. It delivers 5A continuous output current per channel, features CMOS-compatible inputs, multiplexed proportional current sense (K = 650–1200 A/A), and integrated protections including undervoltage/overvoltage shutdown, thermal shutdown, reverse battery protection, and loss-of-ground detection. Used in body control modules for driving lamps, solenoids, and actuators.

For engineers reviewing the VNQ05XSP1613TR datasheet, VNQ05XSP1613TR pinout, VNQ05XSP1613TR application, or VNQ05XSP1613TR equivalent, key selection criteria include on-resistance (110 mΩ @ 25°C), ISO 7637-2 transient immunity (Class C up to Pulse 5a), thermal reset hysteresis (7–15°C), multiplexed analog current sense accuracy (±10% drift over –40°C to +150°C), and PowerSO-16™ package thermal resistance (R_thj-case = 1.6°C/W).

Technical Context

The VNQ05XSP1613TR integrates four independent VIPower M0-3 high-side switches with shared analog current sense mux, enabling per-channel current monitoring via SELA/SELB/SenseEnable logic. Each channel implements active current limiting (5–10 A), thermal shutdown at 150–200°C with 135°C auto-reset, and V_CC clamp (41–55 V) compliant with ISO 7637-2 Pulse 5a.

Its protection architecture includes loss-of-ground detection (auto-shutdown), reverse-battery tolerance (–0.3 V), and short-circuit handling with demagnetization control for inductive loads. The device operates across 5.5–36 V supply range and supports 1.25 V low-level / 3.25 V high-level CMOS input thresholds with 0.5 V hysteresis.

FAQ

What is the maximum continuous output current per channel?

The VNQ05XSP1613TR supports 5A continuous output current per channel at T_case ≤ 25°C with adequate heatsinking. Derating applies above 25°C: R_thj-case = 1.6°C/W limits usable current to ~3.5A at 100°C case temperature under sustained load. Absolute maximum rated current is internally limited to 10A for short-circuit protection.

How does the multiplexed current sense function work?

The C.SENSE pin outputs an analog current proportional to the selected channel's load current, controlled by SELA/SELB and SENSENABLE logic. With SELA=LOW/SELB=LOW and SENSENABLE=HIGH, I_SENSE = I_OUT1/K (K = 650–1200 A/A). Four combinations select channels 1–4; SENSENABLE=LOW places C.SENSE in high-impedance state for bus sharing.

Does this device support reverse battery conditions?

Yes-the VNQ05XSP1613TR tolerates –0.3 V continuous reverse supply voltage on V_CC, and its internal protection network (see page 9 of datasheet) enables safe operation with reverse-battery configurations using either RGND resistor or DGND diode topologies. It does not support sustained –12 V operation.

What transient standards does it meet?

The device complies with ISO 7637-2 for automotive transients: Class C immunity across all test pulses (1–5), including Pulse 5a (+86.5 V, 400 ms, 2 Ω source) and Pulse 1 (–100 V, 2 ms, 10 Ω). This is achieved via integrated V_CC clamp (41–55 V) and robust VIPower M0-3 process design.
