LTC4080XEDD#TRPBF Application Field and Working Principle

Introduction

The LTC4080XEDD#TRPBF is a programmable, Push-button Controlled, dual input, true-OR Charger with a maximum output current of 1.2A and an input current limit of 2A. The LTC4080XEDD#TRPBF is designed to charge two Li-Ion/Li-Polymer batteries (or one battery, then the other battery is put in sleep mode) simultaneously, in a small form factor. This battery charger is an all-in-one device, it contains “an input power selector, an over-voltage, over-current protection circuit, an enable/disable pin and an internal LDO regulator”. All of these features should help to make it easier for manufacturers to use it in their designs.

Functional Block Diagram

The functional block diagram for the LTC4080XEDD#TRPBF is shown below. The functional block diagram basically shows the main components of the device and how the components are connected.

The device is basically comprised of two main blocks, the Power Path Block and the Power Supply Block. The Power Path Block is responsible for making sure that the device charges the battery in an efficient manner. It uses an MOSFET switch and a charge pump to select and regulate the input voltage, allowing it to choose the most efficient input at any given time. The Power Supply Block is responsible for monitoring the voltage and current of both batteries, and is also used to turn on and off the charger.

Application Fields

The LTC4080XEDD#TRPBF is designed to be used for charging two Li-Ion/Li-Polymer batteries. It is used mainly in industrial and automotive applications. It can be used in applications such as industrial unmanned vehicles, drones, robots, car navigation systems and instrumentation systems.

Working Principle

The LTC4080XEDD#TRPBF works by utilizing two main functions, namely power path block control and power supply block control.

Power Path Block Control

The power path block control is responsible for monitoring the input voltage and current and selecting the most efficient input at any given time. This is done using an MOSFET switch and a charge pump. The MOSFET switch is used to regulate the input voltage and the charge pump is used to control the charge current into the battery. The charge current is set using a toggle switch and is adjustable from 0.5 A to 1.2 A.

Power Supply Block Control

The power supply block control ensures that the voltage and current of the batteries is monitored, and it also enables and disables the charger. The device uses two comparators for monitoring the voltage and current of the batteries. When the voltage or current of either battery exceeds the preset threshold, the charger automatically stops charging the battery and enters a sleep mode. The charging process can be re-enabled by pressing the enable/disable pin.

Conclusion

The LTC4080XEDD#TRPBF is a programmable, Push-button Controlled, dual input, true-OR battery charger designed for charging two Li-Ion/Li-Polymer batteries. It works by utilizing two main functions, power path block control and power supply block control. It is mainly used in industrial and automotive applications and is suitable for applications such as industrial unmanned vehicles, drones, robots, car navigation systems and instrumentation systems.
