(The wide core source) recently launched SC7003 (8.4v) double high current (2A) lithium battery charge management controller. SC7003 is a lithium battery for double current / constant voltage charging charging management chip. The chip DC-DC control mode, the frequency of 500KHZ, wide operating voltage range of the chip, the charge current is set by an external resistor to set, providing a high-precision internal reference source to ensure the accuracy of the charging voltage. When the input voltage drops below a set value, the chip enters SLEEP MODE work mode, where power consumption is reduced to within 20μA, while off the charge. The chip by trickle charging, constant current, constant voltage and recharging processes such as composition, external LED can have a variety of charging status display. The chip includes a reference bias voltage comparator and a temperature detection module, SC7003 thermally enhanced 8-pin small outline package SOP8. SC7003 charge management controller can be used in consumer electronics products, such as portable DVD, personal media players (PMP), and portable GPS systems. To ensure high-capacity lithium-ion rechargeable battery and reliable, these fully integrated charge-management controller on a single chip integrates a number of key criteria charging management and security features. Chargers in a small SOP-8 package, easy welding and chip production. Help to achieve a more intelligent, fast and safe battery charger designs. ● Suitable for single, double high-efficiency lithium-ion battery charger design ● 0.5% of the charging voltage control precision smart battery detection ● ● External High Power MOSFET ● Switching Frequency 920KHz / 700KHZ ● programmable charge current control, the maximum charging current can be up to 2A ● NTC thermistor interface monitors the battery temperature ● LED charge status indicator ● Operating ambient temperature range: -20 ℃ ~ 70 ℃ Main products: lithium rechargeable lithium battery management IC double single 8.4V rechargeable lithium-cadmium battery charging ultra tweezers Mouse power boost regulator IC IC DC-DC car charger car charger IC solutions Car LED lighting driver IC output constant current car charger car charger with line fill 60V high voltage regulator IC IC IC 3.7V lithium battery charge management l 5V high current boost boost charger IC LED Driver IC IC IC urgent boost charge current regulator IC LED lights boost driver IC electric toys IC high efficiency boost DC-DC step-down IC Wide Input high current incandescent lamps Driver IC LED flashlight boost IC synchronous rectification IC synchronous buck IC DC / DC step-down IC IC solar lawn low adjustable output voltage detector IC buck IC touch IC 8 key touch IC 6 key touch IC IC Dual Touch Touch key touch IC chip 24-key touch key touch IC 36 key touch IC three-terminal regulator IC LDO LDO 22V power supply 40V buck buck LDO widely core source --- Luo Mobile: 13425146336 Tel: 0755-29469758 27668758 E-mail : mk003@zgsemi.com URL: http: //www.zgsemi.com
