Basic Features
8-bit serial peripheral interface
(daisy-chain capable SPI)
for control and diagnosis
CMOS-compatible parallel input pins
for each channel provide straightforward
PWM operation
Very low standby current
Optimized electromagnetic compatibility
(EMC) for bulbs as well as LEDs
Diagnosis Functions
Multiplexed proportional load current sense signals
current range
Current sense ratio (k
ILIS
) configurable for LEDs or
bulbs (not BTS 5566G)
Very fast diagnosis in LED mode (< 2 % duty cycle
Latching feedback on overtemperature and over
load via SPI
at 100 Hz) (not BTS 5566G)
High accuracy of current sense signal at wide load
Protective Functions
Reverse battery protection with external
components
Short circuit and overload protection
Multistep current limitation
Thermal shutdown with latch
Overvoltage protection
Loss of ground protection
Application Specific Functions
Integration of adjustable watchdog timer with external
capacitor (BTS 5590G only)
increment and lock, served via SPI
Fail-safe activation via LHI pin and configuration
via input pins
(not BTS 5566G)
Load type configuration between bulbs and LEDs
Sophisticated trigger state machine with 2-bit
