A varistor, also known as a Voltage Dependent Resistor (VDR), is a special type of resistor whose resistance varies depending on the applied voltage. Under standard operating voltage, a varistor exhibits high resistance, acting like an open circuit. However, the varistor's resistance drops dramati...

It is advised to set R1 resistance between 100～470Ω. Due to current consumption, R1 should be as small as possible to avoid lowering the overcharge detection accuracy. When a charger is connected in reversed, the current flows from the charger to the IC. At this time, if R1 is connecte...
The training was conducted by Visayas Disaster Response Network (VDRN), a PamCham partner and member of Center for Emergency Aid and Rehabilitation (CONCERN), one of the nongovernment organizations at the forefront of the Pinatubo response in Pampanga, Tarlac and Zambales provinces. Mt. Pinatubo...
Therefore, a Schottky diode with a low forward voltage is recommended. Input Series diode -II Charge pump Reference -IQ Output Regarding the Enable (Inhibit) pin, negative voltages must not be applied. Nevertheless, to allow negative transients to flow, a high-ohmic resistor can be added in ...
