1.4 Pin definitions and functions (cont’d)
Pin No. Symbol Function
11
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.
12
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.
13
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.
14
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.
15
R3
Reset output 3, undervoltage detection for output Q_LDO3;
open drain output; an external pullup resistor of 10kΩ is
required
16
R2
Reset output 2, undervoltage detection for output Q_LDO2;
open drain output; an external pullup resistor of 10kΩ is
required
17
R1
Reset output 1, undervoltage detection for output Q_LDO1 and
watchdog failure reset; open drain output ; an external pullup
resistor of 10kΩ is required
20
C-
Charge pump capacitor connection; Add the fly-capacitor of
100nF between C+ and C-
21
C+
Charge pump capacitor connection; Add the fly-capacitor of
100nF between C+ and C-
22
CCP
Charge Pump Storage Capacitor Output; Add the storage
capacitor of 220nF between pin CCP and GND.
23
SEL
Select Pin for output voltage adjust of Q_LDO2 and Q_LDO3
(see also 2.2.2)
24
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.
25, 26 FB/L_IN Feedback and Linear Regulator Input; input connection for
the Buck converter output
