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 automotive applications. The output stages can be controlled directly by parallel inputs for PWM applications (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. Block Diagram
