FUNCTION
LDO Output-Voltage Select Input 1. SEL1 and SEL2 set the OUT1 and OUT2 voltages to one of nine
combinations (Table 1).
LDO Output-Voltage Select Input 2. SEL1 and SEL2 set the OUT1 and OUT2 voltages to one of nine
combinations (Table 1).
OUT2 Enable Input. Drive EN2 low to enable OUT2. Drive EN2 high to disable OUT2. If the MAX8620Y
is placed into shutdown (PWR_ON = HF_PWR = low), OUT2 does not power regardless of the status
of EN2 (Table 2, Figure 4).
Open-Drain, Active-Low Reset Output. RESET asserts low when V OUT1 drops below 87% (typ) of
regulation. RESET remains asserted for t RP after V OUT1 rises above 87% (typ) of regulation. RESET
also asserts when OUT1 is disabled (Figure 4). RESET deasserts if OUT1 is enabled and V OUT1 is
above 87% of regulation after t RP .
Reference Bypass Capacitor Node. Bypass BP with a 0.01μF capacitor to GND. BP is high
impedance when the MAX8620Y is disabled (PWR_ON = HF_PWR = low).
Hands-Free Enable Input. Drive HF_PWR high or apply a pulse to enable the MAX8620Y. Power is
enabled for 1.31s (typ) following a rising edge at HF_PWR (Table 2, Figure 4).
Power-Enable Input. Drive PWR_ON high to enable the MAX8620Y (Table 2, Figure 4). Drive PWR_ON
low to enter shutdown mode. In shutdown, the LX node is high impedance and both LDOs are
disabled (depending on the state of HF_PWR).
Step-Down Converter Output-Voltage Feedback Input. V FB regulates to 0.6V (typ). Connect FB to the
center of an external resistor-divider between LX and GND to set V OUT3 between 0.6V and 3.3V (see
the Setting the Step-Down Output Voltage (OUT3) section).
Ground. Connect GND to the exposed pad.
Inductor Connection. LX is internally connected to the drain of the internal p-channel power MOSFET
and the drain of the n-channel synchronous rectifier. LX is high impedance when OUT3 is disabled.
Power Input 2. Connect IN2 to IN1 as close to the device as possible.
Power Input 1. Connect IN1 to IN2 as close to the device as possible. Bypass IN1 to GND with a 10μF
ceramic capacitor, as close to the device as possible.
300mA LDO Output 1. Bypass OUT1 to GND with a 4.7μF ceramic capacitor for 300mA applications,
or a 2.2μF ceramic capacitor for 150mA applications. OUT1 is high impedance when disabled.
300mA LDO Output 2. Bypass OUT2 to GND with a 4.7μF ceramic capacitor for 300mA applications,
or a 2.2μF ceramic capacitor for 150mA applications. OUT2 is high impedance when disabled.
Exposed Pad. Connect EP to GND.
