HT4936S контролер заряду SOP16

Контролер заряду Маркування: HT4936S Корпус: SOP-16 The built-in maximum 1 A linear charging mode of charging current is adjustable Технічні параметри: Built-in maximum 1A linear charging mode, charging current can be external Tune ◆ Trickle/constant current/constant voltage three-stage charging, 4.20V/4.35V available Optional, support 0V battery charging; ◆ The built-in charging can automatically reduce the charging current according to the temperature rise, 130 The degree begins to decrease, and the lowest can be reduced to 0; ◆ The booster uses a synchronous rectifier circuit, with the highest efficiency exceeding 90%, low heat generation, fixed 5.1V output, no need for external Resistance setting; ◆ Boost output current 1A (BTP=3.6V); ◆ With constant power output function, complete over-current, short-circuit Protection, built-in temperature protection automatically stops the boost when over temperature; Automatically start boost when load is inserted, and automatically stop when load is removed sleep; ◆ The four-light indicator mode can indicate the battery power more accurately. With battery low voltage reminder function; ◆ There is a port for setting Apple D+, D- voltage divider resistance setting DPDN, with an NTC setting port, can control Control system safe working temperature ◆ It can directly drive the LED flashlight with a drive current of 50mA ◆ Fixed switching frequency 1MHZ ◆ Battery overcharge and overdischarge protection
