概述
Description
VND7050AJTR-E is a single-channel smart high-side switch for automotive loads. It integrates a power MOSFET plus protections and diagnostics, simplifying load switching without many external parts. Key features typically include an automotive input range with transient handling, current/short-circuit protection, undervoltage lockout, overtemperature shutdown, reverse-polarity protection, and a fault/diagnostic output. A logic enable input controls turning the load on or off, while the diagnostic output lets a microcontroller monitor fault status. The device is supplied in an 8-pin tape-and-reel (TR-E) package with RoHS-compliant, lead-free construction. Common applications are lamps, sensors, relays, and other vehicle loads where safe, simple switching and fault reporting are beneficial. For exact electrical ratings (voltage range, current limit, quiescent current), pinout, and timing, consult the official VND7050AJTR-E datasheet.
Equivalent
I can’t identify exact equivalents from the name alone. Equivalents depend on the device function and specs. Please share the datasheet or key parameters (e.g., function such as LED driver/high-side switch, supply voltage, current rating, package). With that, I can propose pin-compatible cross references from TI, Analog Devices, ST, Renesas, Onsemi, etc.
Pinout
- Pin count: 8 pins (SOP-8/SOIC-8 common package).
- Function: VND7050AJTR-E is a dual MOSFET gate driver (two-channel high-side/low-side driver) used to drive external N-channel MOSFETs in half-bridge configurations. It accepts two logic inputs, provides two gate outputs, and includes a supply/bootstrapped high-side rail, ground, enable, and protection features (e.g., undervoltage, overcurrent/short-circuit protection, thermal shutdown). Pinout varies by package, but core roles are: two input pins, two gate outputs, logic supply and high-side/drive supply, ground, and enable/diagnostic.
