Reference Design For A 10A Quick Battery Charger 


The quick charging reference design from Renesas is able to delivering a excessive charging present of 10A. The reference design is as much as 98% environment friendly when the charging present is about at 2Amps. The reference design employs a high-efficiency present doubler with built-in Analog to Digital converters (ADC) for system monitoring. The microcontroller used within the reference design works as a USB transceiver and enhances the discrete digital IO management (Normal Goal Enter Output (GPIO) and devoted capabilities).

The reference design from Renesas can be utilized as a stand-alone 1S charger or may be carried out into Laptops, smartphones, tablets, and so on.

The charger is able to delivering as much as 6A by utilizing the usual Kind C cable. The quick charging is achieved by the doubler circuit that makes use of a high-efficiency capacitive divider. The reference design employs an 8-bit ADC to maintain a test on parameters comparable to enter present, output present, voltage and junction temperature   For software program supervision a programmable watchdog timer, and for battery overload safety a security timer, are included.

The reference design employs two energy monitor IC, that allows the measurement of the principle charger enter voltage and enter present and permits the monitoring of the battery parameters. I2C protocol is used for communication. The block diagram of this reference design is given beneath:
