Tp4056 current resistor

Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4. V, and the charge current can be programmed externally with a single resistor. There is some documentation on the sellers ebay page. The current resistor can be replaced .

The module uses a very small amount of current (in the micro amps) whenever it is connected to a battery. It is fine to leave it connected to a battery for. It works with linear charging method. Hi, I am new here and hope that you can answer a quick question about a little project of mine.


I rea that you can also get lower mA . Current : 1A (Adjustable) Charge precision: 1. V Full charge voltage: 4. If you want to use this to charge from a USB port you would have to replace the resistor which is explained below.

It does not include any power supply or tray. Now one important thing, charging current is determined by resistor connected to PROG pin, modules available in market generally comes with 1. KOhm connected to this pin, which corresponds to Ampere charging current (Image No.5). You can play with this resistor to . However you can change this by changing the 1kresistor next to the IN- pad the bottom-left of the board. This is a linear battery charger controller with constant current and constant voltage. By adding a single programmable resistor the IC can be used to charge a 3. V and charging current can be set by . The default resistor soldered in on the board is 1. Use the following table of resistance and current values to solder the right resistor to obtain the . It has thermal feedback mechanism to regulate the charge current to limit the die temperature during high power operation or high ambient temperature.


I changed the current resistor to 4Kto get 0. A My first intention was to rip the single slot charger . I did a comparison of the programming resistor vs charge current info from the datasheet, and my empirical data seems reasonable. A full charge voltage: 4. The full charge voltage is fixed at 4. V, while the charge current can be adjusted externally through a given single resistor.

This charger is a very small battery charger module. Ideal for adding an embedded battery charger to your new project. Rprog resistor - resistor values for various current levels are specified in .
