STMicroelectronics VND5E008AY-E

Overview

VND5E008AY-E from STMicroelectronics is a double-channel high-side driver IC with integrated analog current sense, designed for automotive resistive/inductive/capacitive load control. It delivers 76 A typical current limitation per channel, 8 mΩ typical on-state resistance at 25°C, and operates across 4.5–28 V supply range. Used in body control modules for headlight, fog lamp, and HVAC blower switching.

For engineers reviewing the VND5E008AY-E datasheet, VND5E008AY-E pinout, VND5E008AY-E application, or VND5E008AY-E equivalent, key selection criteria include its AEC-Q100 qualified PowerSSO-36 package, ±12% current sense ratio drift over temperature, thermal shutdown with automatic restart, and diagnostic reporting via CS pins - all critical for ISO 16750-compliant automotive power distribution systems.

Technical Context

The device implements VIPower® MO-5 technology to integrate dual high-side switches, active power limitation, and proportional analog current sensing in a single die. Each channel features independent CMOS-compatible inputs (IN1/IN2), dedicated current sense outputs (CS1/CS2), and shared CS_DIS control for simultaneous sense disable.

Diagnostic functions are embedded in the analog sense path: off-state open-load detection triggers at 2–4 V on VOUT while IN=0; short-to-VCC is identified by delayed output collapse; overload and thermal events modulate ISENSE amplitude and timing (e.g., tDSENSE2H = 70–300 µs). Protection includes undervoltage lockout (4.5 V), 41 V transient clamp, reverse battery tolerance (-16 V), and self-limiting thermal response with 150 °C shutdown and 135 °C reset.

FAQ

What is the maximum continuous output current per channel?

The VND5E008AY-E does not specify a maximum continuous current rating due to thermal dependence on PCB layout and ambient conditions. Its 76 A current limit is a short-circuit threshold; sustained operation above ~15 A requires careful thermal design using the PowerSSO-36 package's 0.85 °C/W R_thj-case. Derating curves in Figure 26 show ILIMH drops to ~53 A at 150 °C junction temperature.

How does the current sense function during thermal shutdown?

During thermal shutdown, the current sense output (CSx) remains active and reflects actual load current until junction temperature reaches ~175 °C (absolute max), at which point the device latches off. In overload conditions, ISENSE amplitude decreases gradually as power limitation engages, providing early warning before full shutdown - documented in Figure 12 and Table 9.

Can CS_DIS be left unconnected?

No. Per Table 2, CS_DIS must never be left floating. It must be pulled to ground through a 1 kΩ resistor if unused, or driven actively high/low. Floating CS_DIS risks undefined sense behavior, potential latch-up, and failure to meet AEC-Q100 reliability requirements due to noise coupling into the high-impedance analog sense path.

Is the PowerSSO-36 package RoHS and REACH compliant?

Yes. The VND5E008AY-E uses ST's ECOPACK®-qualified PowerSSO-36 package, explicitly stated as compliant with European Directive 2002/95/EC (RoHS) and fully aligned with REACH SVHC requirements. Lead-free soldering profiles and halogen-free molding compound are certified per ST's quality documentation (DocID13620 Rev 5, Section 5.1).
