MAX1613 - Bridge-Battery Backup Controller

Download the MAX1613 datasheet PDF. This datasheet also covers the MAX1612 variant, as both devices belong to the same bridge-battery backup controller family and are provided as variant models within a single manufacturer datasheet.

Description

The MAX1612/MAX1613 manage the bridge battery (sometimes called a hot-swap or auxiliary battery) in portable systems such as notebook computers.

They feature a step-up DC-DC converter that boosts 2-cell or 3-cell bridge-battery voltages up to the same level as the main battery.

MAX1612/MAX1613 19-4785; Rev 0; 11/98 EVFAOLLULAOTWIOSNDKAITTAMSAHNEUEATL Bridge-Battery Backup Controllers for Notebooks General Description The MAX1612/MAX1613 manage the bridge battery (sometimes called a hot-swap or auxiliary battery) in portable systems such as notebook computers. They feature a step-up DC-DC converter that boosts 2-cell or 3-cell bridge-battery voltages up to the same level as the main battery. This voltage boosting technique reduces the number of cells otherwise required for a 6cell plus diode-OR bridging scheme, reducing overall size and cost. Another key feature is a trickle-charge timer that minimizes battery damage caused by constant charging and eliminates trickle-charge current drain on the main battery once the bridge battery is topped off.
