Product Summary
The LTC1729CMS8-4.1#TR is a smart termination controller for lithium-ion battery chargers. These ICs provide trickle charge preconditioning, temperature charge qualification, time or charge current termination, automatic charger and battery detection and status output. Combining the LTC1729CMS8-4.1#TR with the L1510 (1.5A), LT1769 (2A), LT1511 (3A) and LT1505 (> 4A) step-down chargers is a simple operation. Connecting six pins from the LTC1729CMS8-4.1#TR to the step-down chargers completes the integration. The LTC1729CMS8-4.1#TR termination controllers are also compatible with step-down/ step-up (SEPIC) chargers, including the LT1512 (2A switch) and LT1513 (3A switch). The LTC1729 series is available in the 8-pin MSOP and SO packages. Applications are desktop computers, notebook computers, intelligent instruments, portable battery-powered equipment, network servers.
