L99LDLH32
32-channel LED driver with automotive CAN FD Light interface
QFN48L 7x7
Features
AEC-Q100 qualified General
– CAN FD Light compatible Serial Interface, Protocol Handler, Draft Specification Proposal (DSP) available from CAN in Automation (CiA)
– High precision oscillator integrated, no external quartz required
– QFN48L 7x7 with exposed pad – Timeout watchdog with Limp Home – Low standby current – Stand Alone/Fail Safe and Bus mode
operation – Direct drive (1 Direct Input), for 1 function
group supporting ASIL requirements – Widest configurability by embedded
non-volatile and volatile memories – Operating supply voltage range
5.5 V – 40 V
Linear
Regulators section – Operating temperature range - 40°C – 150°C – 32 constant current output channels, high side configuration – Output current from 1 mA to 15 mA, parallelable outputs – Output voltage up to 35 V
Datasheet - production data
– Feedback voltage to external pre-
regulator, to optimize the regulation voltage minimizing overall power dissipation
– Current setting per channel by 8-bit DAC – Analogue dimming, 8-bit PWM channel
individual exponential brightness control and 8-bit global PWM dimming – Programmable PWM frequency – Slow turn on/off time, gradual outputs delay and dithered clock, for better EMC performances
Protection and diagnostic – Integrated 8-bit ADC, for full and flexible diagnostic – 1 dedicated line for fault bus – Temperature warning (1 threshold) – Over-temperature shutdown – Shor...
