General Description

ECL1001 includes a programmable high efficiency BUCK charger, four LED battery indicator, a Torch LED driver, a high efficiency Boost converter, and an overdischarge protector.
It is suitable for single-cell lithium -ion / lithium polymer battery charge and discharge management, and can be widely used in power bank, handheld devices, PDA, smart phones and so on. It integrates high efficiency synchronous BUCK battery charge management , the maximum charging current of up to 2A ; the integrated boost DC / DC can output the maximum discharge current reaches 1.5A , and intelligent judgments load insertion and removal, automatic boost and automatic shutdown; the integrated battery detection and 4 – segment display, both in the state of charge or discharge, can effectively indicate the current battery remaining power.
By a unique key , it can easily control the boost switch start and Torch On/off.
Torch LED can output maximum 50mA of current. ECL1001 also integrates a battery temperature detection, low battery voltage protection, output over current / over voltage / short circuit protection circuit to ensure that chip and system security.
