         CSC5289 is a PWM boost voltage type multi section nickel hydrogen battery charging management chip, with a USB 5V power input. It manages the constant current charging of 1 to 8 nickel hydrogen batteries through PWM boost voltage control. CSC5289 has a built-in reference voltage source, a high-precision ADC module to detect charging current and battery voltage, an integrated off chip field-effect transistor driver circuit, and LED lights to indicate charging status. It has the advantages of fewer external components, high conversion efficiency, and simple circuit.
