LTC3351 Overview
Key Specifications
Package: QFN
Pins: 44
Description
The LTC®3351 is a backup power controller that charges and monitors a series stack of one to four supercapacitors. The LTC3351’s synchronous step-down controller drives N-channel MOSFETs for constant current/constant voltage charging with programmable input current limit.
Key Features
- High Efficiency Synchronous Step-Down CC/CV Charging of One to Four Series Supercapacitors
- Programmable Undervoltage and Overvoltage Thresholds to 35V
- VIN: 4.5V to 35V, VCAP(n): Up to 5V per Capacitor, Charge/Backup Current: >10A
- Programmable Input Current Limit Prioritizes System Load Over Capacitor Charge Current
- All N-FET Charger Controller and PowerPath™ Controller
