STMicroelectronics VND5E008ASPTR-E

Overview

VND5E008ASPTR-E from STMicroelectronics is a dual-channel automotive high-side driver in PowerSO-16 package, designed for 12 V grounded loads with integrated analog current sensing, thermal shutdown with auto-restart, 7.7 mΩ typical on-resistance per channel, and 85 A current limitation. It delivers diagnostic feedback via dedicated CS1/CS2 pins and supports 3 V/5 V CMOS-compatible microcontroller interfacing in body control modules.

For engineers reviewing the VND5E008ASPTR-E datasheet, VND5E008ASPTR-E pinout, VND5E008ASPTR-E application, or VND5E008ASPTR-E equivalent, key selection criteria include its dual-channel high-side topology, ±41 V transient supply tolerance, off-state open-load detection, short-to-VCC diagnosis, and active power limitation for inrush/overload management in safety-critical automotive systems.

Technical Context

The device implements two independent VIPower® M0-5 high-side switches with integrated current sense amplifiers delivering proportional I_OUT/I_SENSE ratios (e.g., 3550–9350 at 0.5 A), thermal shutdown at 150–200 °C with 7 °C hysteresis, and undervoltage lockout at 3.5–4.5 V. Each channel features active clamp protection against load dump transients up to 41 V and reverse battery tolerance down to –16 V.

Diagnostic functions are hardware-synchronized: CS_DIS enables/disables current sense outputs, while fault states-including overload (power-limited), short-to-GND, short-to-VCC, and off-state open-load-drive V_SENSE to defined high-level (8 V) or high-impedance conditions per truth table behavior. Switching delays are tightly controlled (t_d(on) = 28 µs typ, t_d(off) = 15 µs typ) under 13 V supply and 25 °C junction temperature.

FAQ

What is the maximum continuous output current per channel?

The VND5E008ASPTR-E does not specify a fixed maximum continuous current rating; instead, it implements active current limitation at 60–120 A depending on supply voltage and thermal conditions. Sustained current is determined by thermal design: with proper PCB copper area (≥200 cm²), continuous operation up to 10 A per channel is achievable at 125 °C ambient, based on R_thj-amb curves in Figure 19.

How does off-state open-load detection work?

Off-state open-load detection activates when INx = 0 V and V_OUTx rises above 2–4 V due to leakage through an unconnected load. The internal circuitry pulls V_SENSE to 8 V (V_SENSEH) to signal the condition. This requires an external pull-up resistor (10 kΩ recommended) on the output to generate the detectable voltage rise, as specified in Table 10 and Figure 12.

Can CS1 and CS2 be used simultaneously with a shared sense resistor?

Yes - pulling CS_DIS high disables both current sense outputs, placing them in high-impedance state and allowing external circuitry to share a single sense resistor between multiple VND5E008ASPTR-E devices. When CS_DIS is low, each CS pin sources its own proportional current; simultaneous use with shared resistor is not supported in enabled mode due to interaction between sense paths.

Is reverse battery protection active during sleep mode?

Yes - reverse battery protection remains fully functional even with IN1/IN2 held low and no load connected. The integrated self-switching PowerMOS blocks reverse current flow down to –16 V DC, and off-state supply current remains at 2 µA typ, ensuring zero power drain from the battery during vehicle ignition-off periods.
