Controller IC Chip - MOFSET BQ24753ARHDT BQ24753A BQ24753 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0345) Host-Controlled Li-Ion and Li-Polymer Battery Charger With Low Iq and System Power Selector The bq24753A is a high-efficiency, synchronous battery charger with integrated compensation and system power selector logic, offering low component count for space-constrained Li-Ion and Li-Polymer battery charging applications. Ratiometric charge current and voltage programming allows for high regulation accuracies, and can be either hardwired with resistors or programmed by the system power-management microcontroller using a DAC or GPIOs. The bq24753A charges two, three, or four series Li+ cells, supporting up to 10 A of charge current, and is available in a 28-pin, 5x5-mm thin VQFN package.  NMOS-NMOS Synchronous Buck Converter with 300 kHz Frequency and >95% Efficiency 30-ns Minimum Driver Dead-time and 99.5% Maximum Effective Duty Cycle High-Accuracy Voltage and
