General Description

The TPAFE411 is designed only for Hall elements to use in closed-loop current-sensor modules.

The internal precision excitation circuitry for the Hall-element could effectively eliminate the offset and offset-drift of the Hall element.

The TPAFE411 also provides a 350mA H-bridge for driving the sensor compensation coil, and an internal precision current sensing amplifier to generate the output signal.
