How does a charger detector work?
When you combine the charger detection and battery-charging functions, you have smart battery switch control. This technology automatically switches from battery power to charger power when a charger is present. Consequently, some charger detector chips can both charge a battery and provide full-load current.
What is a charger detection IC?
Consequently, charger detection ICs are highly integrated with a myriad of additional features such as built-in switches for USB or UART/audio operation, serial control interfaces, overvoltage protection (OVP), USB OTG support, Li+ battery charging capability, or even the ability to perform USB enumeration.
What is the Charger detection phase outlined in bc1.2?
The charger detection phase outlined in BC1.2 has five basic steps. VBUS detection To ensure proper sequencing for any potential devices connected to a USB port, the V BUS and GND pins on the connector are intentionally made longer than the D+ and D- pins. This ensures that they make contact first (see Figure 1).
How complex is a battery charging system?
The complexity (and cost) of the charging system is primarily dependent on the type of battery and the recharge time. This chapter will present charging methods, end-of-charge-detection techniques, and charger circuits for use with Nickel-Cadmium (Ni-Cd), Nickel Metal-Hydride (Ni-MH), and Lithium-Ion (Li-Ion) batteries.
Why should you choose a single Charger detector?
When you consider the built-in OVP on the V BUS pin, the ESD protection on the data lines, and the 1.65mm x 1.65mm footprint, this single charger detector adds considerable versatility in a single connector for space-constrained designs.
How does a -DV detector work?
This drop in battery voltage is used to terminate fast charge in a -DV Detector, which continuously monitors the battery voltage and shuts off the charger when the voltage drops by a pre-set amount.
