DC364A-B Overview

board eval for ltc1732ems

Quick Start Guide for
Demo Board DC364A-A and DC364A-B
Demonstration boards DC364A-A and DC364A-B are complete constant-current/constant-voltage
battery chargers designed to charge one Lithium-Ion cell. Both feature the LTC1732 Linear
Battery Charger driving a P-channel MOSFET in a series pass linear regulator configuration for
charging at a maximum current of 700mA (limited by the power dissipation capabilities of the
pass transistor).
Demo board DC364A-A features the LTC1732-4, which has a recharge threshold voltage of 3.8V,
making it suitable for charging 4.1V or 4.2V cells (selectable by jumper on the demo board).
Demo board DC364A-B features the LTC1732-4.2, which is recommended only for charging a
4.2V cell, due to its recharge threshold voltage of 4.05V.
Other Features include:
Preset float voltages of 4.1 and 4.2V ± 1% (DC364A-A)
700mA Constant Current (can be programmed for other charge currents)
3-hour charge termination timer. This timer can be set for other time periods through a
capacitor change. For instance, you may want to use a much shorter period (on the order of
30 seconds) when evaluating the board with a battery simulator instead of a Li-Ion battery.
Manual Shutdown
C/10 Trickle charge for deeply discharged batteries
Auto recharge when battery voltage drops below preset threshold (3.8V for DC364A-A and
4.05V for DC364A-B).
Low battery drain current when the input supply is removed
Input Power OK LED indicator (ACPR)
C/10 Charge LED indicator (CHRG)
Small surface mount components are used to minimize board space and height with the circuitry
occupying approximately 0.15 square inches of board space with a height of 0.054 inches
(1.4mm).
