UG116 Rev 2.0, 17-Jul-2019 EA2804QJ-T and EA2804QJ-T0435 Users Guide 5V/3.4A Dual Cell Backup Battery Power Manager Description This document supports both the EA2804QJ-T and the EA2804QJ-T0435 Evaluation Kits. These kits are a proven application-circuit design for the ACT2804QJ-T and ACT2804QJ-T0435 dual cell chargers with power path and single USB outputs. The EVKs contain a single micro-USB input and USB output. They provide two outputs, one at 2.4A and one at 1A. They are configured to charge a 2S Lithium-ion battery with 1.0A. The EVKs operate with very high charge efficiency of 91% and discharge efficiency of 92%. EVKs are identical except for the IC. The ACT2804QJ-T EOC (end of charge voltage) is 4.2V per cell (8.4V total) while the ACT2804QJ- T0435 EOC is 4.35V for each cell (8.7V total). Features The EVK contains a high efficiency Buck and Boost DC/DC converter that operates either in CV (Constant Voltage) mode or CC (Constant Current) mode. The EVK provides up to 3.4A output current at 400 kHz switching frequency. It operates from VIN=4.5V to 5.5V and provides an output voltage of 5V. Gerber files are available to minimize time-to-market for applications that want to use the EVK as an end-product.
