HT4936S is a new architecture of single-chip mobile power management chip, using advanced charging and discharging port sharing technology, as well as synchronous rectification technology, fewer peripheral components, excellent performance, can build a good 1A-in\/1A-out 4LEDs mobile power supply.
HT4936S is a new architecture of single-chip mobile power management chip, using advanced charging and discharging port sharing technology, as well as synchronous rectification technology, fewer peripheral components, excellent performance, can build a good 1A-in\/1A-out 4LEDs mobile power supply. ◆ Built-in maximum 1A linear charging mode, charging current can be adjusted externally;
◆ Trickle\/constant current\/constant voltage three-stage charging, 4.20V\/4.35V optional, support 0V battery charging;
◆ Built-in charging can automatically reduce the charging current according to the temperature rise, start to drop at 130 degrees, and the lowest can be reduced to 0;
◆ The use of synchronous rectifier circuit, the maximum efficiency of more than 90%, low heating, fixed 5.1V output, no need for external resistance Settings;
◆ Boost output current 1A(BTP=3.6V)
; ◆ With constant power output function, complete overcurrent, short circuit protection, built-in temperature protection over temperature automatic stop voltage boost; ◆ Load insertion automatically starts voltage boost, load removal automatically hibernates;
◆ Four-light indicator mode, more accurate indication of battery power, while with battery low voltage reminder function;
◆ With a set Apple D, D-partial voltage resistance setting port DPDN, with an NTC setting port, you can control the safe operating temperature of the system; ◆ Can directly drive LED hand lamp, drive current 50mA; ◆ Fixed switching frequency 1MHZ;
◆ Battery overcharge, overdischarge protection;
◆ 4KV ESD;
◆SOP16 package;
