with higher inrush currents as current limitation

value (for OUT1-6, OUT7, OUT8 and

OUT_HS) with thermal expiration feature

? All the embedded outputs come with protection

and supervision features:

– Current Monitor (high-side only)

– Open-load

– Overcurrent

– Thermal warning

– Thermal shutdown

? Fully protected driver for external MOSFETs in

H-bridge configuration

? Two 5 V voltage regulators for microcontroller

and peripheral supply

? Programmable reset generator for power-on

and undervoltage

? Configurable window watchdog

? LIN 2.2a compliant (SAEJ2602 compatible)

transceiver

? Separated (Isolated) fail-safe block with 2 LS

(RON = 1 ?) to pull down the gates of the

external HS MOSFETs

? Thermal clusters

? A/D conversion of supply voltages and internal

temperature sensors

? Embedded and programmable VS duty cycle

adjustment for LED driver outputs
