The DC1568A is a 2A monolithic multi-chemistry battery charger for solar power applications.
The document details the DC1568A demonstration board, which features the LT3652EDD 2A monolithic multi-chemistry battery charger designed for solar power applications. The charger supports a wide input voltage range of 11.5V to 32V and provides constant current/constant voltage (CC/CV) charging with a maximum current of 2A. It includes features such as battery preconditioning, bad battery detection, and automatic charge cycle restart.
| Input Voltage Range | 11.5V to 32V |
|---|---|
| Output Float Voltage | 8.2V |
| Output Current Limit | 2A |
| Package Type | 12-lead DFN |
The maximum charge current is 2A, which is programmed by an external inductor current sense resistor.
Yes, it triggers a system fault if a battery stays in precondition mode for more than one-eighth of the total charge cycle time.
The charger suspends charging and signals a fault if the battery temperature moves outside the range of 0°C to 50°C.
