nanoPower On/Off Controller with
Programmable Sleep Time
MAX16163/MAX16164
General Description
Benefits and Features
The MAX16163 and MAX16164 are nanopower on/off
controllers with programmable sleep time. The devices in-
tegrate a power switch to gate an output, which provides
up to 200mA load current.
● Ultra Low Current Saves Power
• 30nA I in SLEEP_TIMER State
Q
• 10nA I in SHUTDOWN State
Q
• VCC Range: 1.7V to 5.5V
The MAX16163/MAX16164 use either an external resistor
to program the sleep time or program the sleep time
through an I C bus. When the device powers up, it checks

• I C or Resistor Programmable Sleep Time
When the MAX16163 powers up, it measures the resis-
tance on the PB/SLP pin to the ground and sets the sleep
time properly. It then asserts the OUT output. When the
downstream device (e.g., a μC) finishes its task, it asserts
a falling edge on the CLRB pin; the MAX16163 then de-
asserts OUT and the sleep timer starts. When the sleep
timer expires, the MAX16163 asserts OUT again.
• Interrupt Output and Clear Input in Resistor
Programmable Configuration
• Up to 32 Different Sleep Time Values from 100ms
to 24 Hours, and Infinite
• Latched Output Supplies 200mA Load Current With
Less Than 30mV Drop
When the MAX16164 powers up, it measures the resis-
tance on the PB/SLP pin to the ground and sets the sleep
time properly. It then keeps OUT deasserted and puts the
device in SHUTDOWN state. The MAX16164 does not as-
sert OUT until a pushbutton closure on the PB/SLP pin.
