General Description

Dual Current Sense Low-Side Switch in Smart Power Technology (SPT) with two open drain DMOS

output stages. The TLE 6214 L is protected by embedded protection functions and designed for auto-

motive applications. The output stages can be controlled directly by parallel inputs for PWM applica-

tions (e.g. Oxygen Probe Heater, Stepper Motor) or by SPI. All output stages can provide a load current

proportional sense signal. Diagnosis is done by an 8 bit SPI or by one status output per channel.
