Details

The LTC4053 is a standalone linear lithium-ion battery charger IC designed by Linear Technology (now part of Analog Devices). It provides a complete constant-current/constant-voltage charge profile for single-cell lithium-ion batteries. The device operates from a USB port or an AC adapter input, making it ideal for portable devices like smartphones, tablets, and portable media players.Some key features of the LTC4053 include a programmable charge current up to 800mA, a 4.2V float voltage, and a thermal regulation circuit that adjusts the charge current to limit the die temperature during high power operation. The charge cycle terminates when the charge current drops to one-tenth of the programmed current, and an onboard timer prevents prolonged charging in case of a fault condition.Additionally, the LTC4053 includes programmable inputs for selecting charging profiles, as well as status pins for indicating charge termination and fault conditions. The device is housed in a small 10-lead DFN package, making it suitable for space-constrained applications.

The charger also includes under-voltage lockout and thermal shutdown protection for added reliability.

How Many Pins does LTC4053 have and What are the Functions of the Pinout Configuration?

The LTC4053 is housed in a 10-lead MSOP (Mini Small Outline Package) package. The pinout configuration includes:

VIN: Input power supply pin.
GATE: Charge enable control pin.
PROG: Charge current programming pin.
BAT: Battery connection pin.
REG: Output voltage regulation pin.
STAT1, STAT2: Charge completion and fault status pins.
TS: Thermistor input for thermal regulation.
GND: Ground pin.

What are the Pros and Cons of LTC4053?

Pros:

Standalone Operation: Does not require a microcontroller or external components for charging control.
Thermal Regulation: Includes thermal regulation to optimize battery life and safety during charging.
Automatic Recharge: Automatically restarts charging if battery voltage drops below a preset level.
Compact Package: Housed in a space-saving MSOP package, suitable for compact designs.
Charge Status Indication: Provides charge completion and fault status indications for system monitoring.

Cons:

Single-Cell Charging: Designed specifically for single-cell lithium-ion battery charging.
