Pin 

Name 

Function 

V3.3 

Input voltage supply between 2.7-5V. 

V16 

Output voltage preset to 16V. 

SHTDN 

Shutdown input. A logic high puts the MAX8574 into normal 
operation. A logic low at SHTDN places the MAX8574 into low-
power shutdown mode. Does not have pulldown resistor for 
disable.
