Product data sheet
2.5 Control and Diagnostic features
2.6 Voltage regulators
Standby mode with very low standby current and full wake-up capability; V1 active to
maintain supply to the microcontroller
Sleep mode with very low sleep current and full wake-up capability
Safe and predictable behavior under all conditions
Programmable watchdog with independent clock source:
16-bit Serial Peripheral Interface (SPI) for configuration, control and diagnosis
Global enable output for controlling safety-critical hardware
Limp home output (LIMP) for activating application-specific ‘limp home’ hardware in
the event of a serious system malfunction
Overtemperature shutdown
Interrupt output pin; interrupts can be individually configured to signal V1/V2
undervoltage, CAN/LIN/local wake-up and cyclic and power-on interrupt events
Bidirectional reset pin with variable power-on reset length to support a variety of
microcontrollers
Software-initiated system reset
Main voltage regulator V1:
Voltage regulator V2 for CAN transceiver:
Output signal (WBIAS) to bias the wake pins, selectable sampling time of 16 ms or
64 ms
Window, Timeout (with optional cyclic wake-up) and Off modes supported (with
automatic re-enable in the event of an interrupt)
Scalable voltage regulator for the microcontroller, its peripherals and additional
external transceivers
±2 % accuracy for LIN master application
±3 % accuracy for LIN slave application
3.3 V and 5 V versions available
Delivers up to 250 mA and can be combined with an external PNP transistor for
better heat distribution over the PCB
Selectable current threshold at which the external PNP transistor starts to deliver
current
Undervoltage warning at 90 % of nominal output voltage and undervoltage reset at
90 % or 70 % of nominal output voltage
Can operate at V
with ISO7637 pulse 4/4b and ISO16750-2
Stable output under all conditions
Dedicated voltage regulator for on-chip high-speed CAN transceiver
Undervoltage warning at 90 % of nominal output voltage
Can be switched off; CAN transceiver can be supplied by V1 or by an external
voltage regulator
Can operate at V
with ISO7637, pulse 4
Stable output under all conditions
