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.
