U2482B Datasheet

(u2481b / U2482b) Automotive Lamp Outage Monitor

Manufacturer: TEMIC Semiconductors (now Microchip)

This datasheet includes multiple variants, all published together in a single manufacturer document.

U2482B Overview

The U2481B and the U2482B multiparator circuits are designed to monitor automotive illumination by sensing the voltage drop across shunt resistors. Provided with extremely low parator thresholds, these ICs can be used together as a chip set to build an entire lamp monitor system. Single operation of both circuits is also possible.

U2482B Key Features

  • Human body model: 4 kV
  • Machine model: 200 V EMI protection (TEM cell up to 100 V/m)
