2.3
Voltage Trackers
For off board supplies i.e. sensors six voltage trackers Q_T1 to Q_T6 with 17mA output
current capability each are available. The output voltages match Q_LDO1 within
+5 / -15mV. They can be individually turned on and off by the appropriate SPI command
word sent by the microcontroller. A ceramic capacitor with the value of 1μF at the output
of each tracker is sufficient for stable operation without oscillation.
The tracker outputs can be connected in parallel to obtain a higher output current
capability, no matter if only two or up to all six trackers are tied together. For uniformly
distributed current density in each tracker internal balance resistors at each output are
foreseen internally. By connecting two sets of three trackers in parallel two sensors with
more than 50mA each can be supplied, all six in parallel give more than 100mA.
The tracker outputs can withstand short circuits to GND or battery in a range from -4 to
+40V. A short circuit to GND is detected and indicated individually for each tracker in the
SPI status word. Also an open load condition might be recognised and indicated as a
failure condition in the SPI status word. A minimum load current of 2mA is required to
avoid open load failure indication. In case of connecting several trackers to a common
branch balancing currents can prevent proper operation of the failure indication.
2.4
Standby Regulator
The standby regulator is an ultra low power 2.5V linear voltage regulator with 1mA output
current which is on all the time. It is intended to supply the microcontroller in stop mode
and requires then only a minimum of quiescent current (<30μA) to extend the battery
lifetime.
2.5
Charge Pump
The 1.6 MHz charge pump with the two external capacitors will serve to supply the base
of the NPN linear regulators Q_LDO1 and Q_LDO3 as well as the gate of the Buck
DMOS transistor in 100% duty cycle operation at low battery condition. The charge pump
voltage in the range of 8 to 10V can be measured at pin 22 (CCP) but is not intended to
be used as a supply for additional circuitry.
2.6
Power On Reset
A power on reset is available for each linear voltage regulator output. The reset output
lines R1, R2 and R3 are active (low) during start up and turn inactive with a reset delay
time after Q_LDO1, Q_LDO2 and Q_LDO3 have reached their reset threshold. The
reset outputs are open drain, three pull up resistors of 10k ? each have to be connected
to the I/O rail (e.g. Q_LDO1) of the μC. All three reset outputs can be linked in parallel to
obtain a wired-OR.
The reset delay time is 8 ms by default and can be set to higher values as 16 ms, 32 ms
or 64 ms by SPI command. At each power up of the device in case the output voltage at
