TP4059 Tuowei dual light indicator 600mA linear lithium-ion battery charger advantage product

Dual LED Indication 600mA Linear Li-Ion Battery Charger

describe

TP4059 is a complete single-cell lithium-ion battery charger, with reverse polarity protection of positive and negative poles of the battery, with a larger charging current of 600mA and a more stable current consistency. Its constant current/constant voltage linear control, SOT package and low external component count make the TP4059 ideal for portable applications. The TP4059 can work with both USB power and adapter power.

External sense resistors and blocking diodes are not required due to the use of an internal PMOSFET architecture, coupled with a reverse charge protection circuit. Thermal feedback automatically adjusts the charge current to limit the die temperature during high power operation or high ambient temperature conditions. The full voltage is fixed at 4.2V, while the charge current can be set externally with a resistor. When the battery reaches 4.2V, the charging current drops to 1/10 of the set value, and the TP4059 will automatically terminate the charging.

When the input voltage (AC adapter or USB power supply) is removed, the TP4059 automatically enters a low current state and the battery leakage current is below 2uA. Other features of the TP4059 include a charge current monitor, undervoltage lockout, automatic recharge, and two status pins to indicate end of charge and input voltage engagement.

Users who have already started the iPhone 11 series should pay attention, Apple has built a new performance management system into the phone.

According to Apple's official statement, this new system can include longer application startup time, lower frame rate, Wi-Fi slowdown, backlight dim or lower depending on the battery status and the tasks the iPhone is running. volume status.

Apple also pointed out that as the iPhone 11 is used for longer and the battery ages, the built-in energy management system will slow down the phone, reduce video quality, and reduce volume and display brightness. It's on to give the user the best possible performance as the battery ages."

From a starting point, Apple wants to allow users to experience price performance with a better battery, but it's taking a wrong approach.

Some netizens believe that Apple can simply tell users that the battery capacity is only 75% or 60% of the initial capacity, and ask users what steps to take next. If the user is willing to sacrifice battery life to maintain performance, that's fine; if the user chooses to extend the battery life, there's nothing wrong with that
