Q_T4

Voltage Tracker Output T4 tracked to Q_LDO1; bypass with a

1µF ceramic capacitor for stability. It is switched on and off by

SPI command. Keep open, if not needed.

Q_T5

Voltage Tracker Output T5 tracked to Q_LDO1; bypass with a

1µF ceramic capacitor for stability. It is switched on and off by

SPI command. Keep open, if not needed.

Q_T6

Voltage Tracker Output T6 tracked to Q_LDO1; bypass with a

1µF ceramic capacitor for stability. It is switched on and off by

SPI command. Keep open, if not needed.

Q_LDO3

Voltage Regulator Output 3; 3.3V or 2.6V output; output

voltage is selected by pin SEL (see also 2.2.2); For stability a

ceramic capacitor of 470nF to GND is sufficient.

Reset output 3, undervoltage detection for output Q_LDO3;

open drain output; an external pullup resistor of 10k

Ω is

required

Reset output 2, undervoltage detection for output Q_LDO2;

open drain output; an external pullup resistor of 10k

Ω is

required

Reset output 1, undervoltage detection for output Q_LDO1 and

watchdog failure reset; open drain output ; an external pullup

resistor of 10k

Ω is required

C-

Charge pump capacitor connection; Add the fly-capacitor of

100nF between C+ and C-

C+

Charge pump capacitor connection; Add the fly-capacitor of

100nF between C+ and C-

CCP

Charge Pump Storage Capacitor Output; Add the storage

capacitor of 220nF between pin CCP and GND.

SEL

Select Pin for output voltage adjust of Q_LDO2 and Q_LDO3

(see also 2.2.2)

Q_LDO2

Voltage Regulator Output 2; 3.3V or 2.6V output; output

voltage is selected by pin SEL (see also 2.2.2); For stability a

ceramic capacitor of 470nF to GND is sufficient.
