Typical applicaTions
12V to 32V 2A Charger with C/10 Termination.
A Dual LT6004 Provides Thermal Foldback, Reducing Maximum Charge Current for Temperatures Higher Than 35°C
12V to 32V 2A Charger with Three Hour EOC Termination and
Removable Battery Pack. The RNG/SS Pin Is Used to Reduce the
Maximum Charge Current if 12V < V
IN
< 20V; Input UVLO = 10V.
NTC Range Is Extended to +45C. The Charger Can Supply Loads Up
to the Maximum Charge Current with No Battery Connected
