STMicroelectronics VND600SP13TR

Overview

VND600SP13TR from STMicroelectronics is a dual-channel high-side solid-state relay IC designed for driving resistive or inductive loads with one side grounded. It features 30 mΩ R_DS(on) per channel, 25 A DC short-circuit current capability, proportional analog current sense outputs (K ≈ 4400), and integrated protections including thermal shutdown, over-voltage clamp (41–55 V), under-voltage shutdown (3–5.5 V), and reverse battery protection. It is used in automotive body control modules for headlamp, fog lamp, and HVAC blower switching.

For engineers reviewing the VND600SP13TR datasheet, VND600SP13TR pinout, VND600SP13TR application, or VND600SP13TR equivalent, key selection criteria include channel independence, real-time load current monitoring via ISENSE pins, ISO 7637-2 transient immunity, and PowerSO-10 thermal performance in constrained PCB layouts.

Technical Context

The VND600SP13TR integrates two independent VIPower M0-3 high-side switches with dedicated CMOS-compatible inputs (V_IL = 1.25 V, V_IH = 3.25 V) and isolated analog current sense outputs (I_OUT/I_SENSE ratio = 4400 ±6% at 5 A). Each channel implements autonomous protection logic: thermal shutdown triggers at 150–200 °C with 135 °C hysteresis, and over-voltage shutdown activates at 36 V nominal with clamping up to 55 V.

It operates across 5.5–36 V supply range and supports load dump transients per ISO 7637-2 Pulse 1 (−100 V), Pulse 2a (+100 V), and Pulse 5a (+86.5 V). The device turns off upon ground disconnection and includes internal V_CC clamp diodes to absorb low-energy spikes without external components.

FAQ

What is the maximum continuous output current per channel?

The VND600SP13TR supports 25 A DC short-circuit current per channel, but continuous current is thermally limited. At T_c = 25 °C with recommended PCB copper (6 cm²), maximum continuous current is ~12 A. Derating is required above 25 °C case temperature per Figure 13; at 100 °C case, continuous current drops to ~5 A to maintain junction temperature below 150 °C.

How does the current sense output scale with load current?

The current sense output delivers I_SENSE = I_OUT / K, where K = 4400 ±6% at 5 A (Table 8). For example, a 5 A load produces 1.14 mA into a 3.9 kΩ resistor, yielding 4.44 V at the sense pin. Sense delay is 500 µs (t_DSENSE), and output impedance rises to 400 Ω during thermal shutdown to preserve signal integrity.

Can unused input or sense pins be left floating?

No. Per Table 2, unused INPUT pins must be tied to GND through a 10 kΩ resistor to prevent noise-induced switching; unused CURRENT SENSE pins should be left floating. N.C. pins (9 and 10) may be left unconnected or tied to GND - neither affects functionality, but grounding improves mechanical stability during reflow.

Does the device meet automotive EMC requirements out-of-the-box?

Yes. The VND600SP13TR complies with ISO 7637-2 for conducted transients (Pulses 1, 2a, 3a/b, 4, 5a) without external protection components. Its integrated V_CC clamp and fast thermal shutdown ensure functional safety during load dump events. However, board-level layout (e.g., minimized loop area, ground plane integrity) remains critical to pass full CISPR 25 radiated emissions testing.
