ANALOG CIRCUITRY
operating conditions. A fully configurable window watchdog
circuit will reset the connected MCU in case of an overflow.
Two low power modes are available with several different
wake-up sources to reactivate the device. One analog / digital
input can be sensed or used as the wake-up source. The
device is capable of sensing the supply voltage (VSENSE)
and the internal chip temperature (CTEMP).
HIGH SIDE DRIVERS
with PWM capability are provided to drive small loads such as
Status LED’s or small lamps. Both Drivers can be configured
for periodic sense during low power modes.
MCU INTERFACE
through a standard 8-Bit SPI interface. Critical system events
such as Low- or High-voltage/Temperature conditions as well

as over-current conditions in any of the driver stages can be
reported to the connected MCU via IRQ or RST. The High
Side driver outputs can be controlled via the SPI register as
well as the PWMIN input. The integrated LIN physical layer
interface can be configured via SPI register and its
communication is driven through the RXD and TXD device
pins. All internal analog sources are multiplexed to the
ADOUT0 pin.
VOLTAGE REGULATOR OUTPUTS

supply a MCU with a precise 5.0 V. The switchable HVDD
output is dedicated to supply small peripherals as hall
sensors.
