Application Areas

Independent two-channel DC/DC output (5V/3A+5V/2A)Type-C Power Bank.

Reduced components

Automatic Type-C In/Out detection function without requiring external identification IC. Internal ±1% VREF without requiring external reference voltage source. 4-stage LED power display.

Complete protection

Including over voltage protection, over current protection and over temperature protection functions for the charge/discharge battery terminal.

 

With regard to power bank products, Holtek has released the Power Bank ASSP Flash MCU, the HT45F5N.In addition to the necessary integrated buck/boost PWM control and power display management functions for power bank products, the device also includes a new Type C USB interface and In/Out bidirectional functions. The HT45F5N can auto detect whether the connected device is either a charger or a mobile phone and consequently whether to execute an input charge function or an output discharge function.
A single-cell lithium battery two-channel output (5V/3A+5V/2A) Type-C power bank is designed using the HT45F5N device in this power bank application solution. This solution supports battery charge/discharge functions and automatically detects the insertion of external charger power supplies as well as Type-C In/Out bidirectional discrimination.
Holtek provides technical data such as block diagrams, application circuits, PCB, BOM, etc, to assist users with their rapid product development.
