addresses the system power supply needs for applications
using the Freescale 32-bit microcontroller family architecture.
HARDWARE RESET TIMER (HRT)
delays for the Reset outputs. This delay is programmed by an
external resistor to GND.
VKAM RESET (RSTKAM)
supply to the microprocessor. This output is actively pulled
low when the VKAM output voltage falls below its reset
threshold level.
VDDH RESET (RSTH)
VDDH regulator. This output is actively pulled low when the
VDDH output voltage falls below its reset lower threshold
level or when the VDDH output voltage exceeds its reset
upper threshold level
VDDL RESET (RSTL)
regulator. This output is actively pulled low when the VDDL
output voltage falls below its reset threshold level.
VDD3 RESET (RST3)
regulator. This output is actively pulled low when the VDD3
output voltage falls below its reset threshold level.
VREF OUTPUT 2 (VREF2)
output supplies sensors outside of the electronic control
module and therefore it is protected against a battery short
and short to -1.0 V. This pin is supplied from the V
through the internal protection FET.
VDDL REGULATOR (VDDL)
emitter of VDDL regulator external NPN pass transistor is
connected to this pin.
VDDH REGULATOR (VDDH)
regulator. This pin is also a power input for the protected
outputs VREF1 and VREF2.

VREF OUTPUT 1 (VREF1)
output supplies sensors outside of the electronic control
module and therefore it is protected against short battery and
short to -1.0 V. This pin is supplied from the V
internal protection FET.
