TLE8881-2 - Alternator Controller

General Description

The device is based on Infineon’s power technology SPT which allows bipolar and CMOS control circuitry to be integrated with DMOS power devices on the same monolithic circuitry.

The battery voltage is regulated at a precise value between 10.6 V and 16 V.

Key Features

  • Single-chip alternator control IC.
  • High-side n-channel DMOS output stage with RDSON of 60 mΩ typ. (at 25°C) / 110 mΩ max.
  • Excitation PWM duty cycle range from 0% up to 100%.
  • Full digital and fast PI regulator.
  • EEPROM for customization to the target.
