2.5 Voltage regulator V1
Package
Name
HTSSOP32
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 undervoltage,
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
Scalable voltage regulator for the microcontroller, its peripherals and additional
external transceivers
±2 % accuracy
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
ISO 7637 pulse 4/4b and ISO16750-2
Stable output under all conditions
Window, Timeout (with optional cyclic wake-up) and Off modes supported (with
automatic re-enable in the event of an interrupt)
