Introduction to TPS51206DSQT
The TPS51206DSQT tiny synchronous buck battery charger controller provides a solution for space-constrained applications such as mobile phones and portable devices. The device requires very few external components for the power delivery to the battery. The integrated power stage includes an N-Channel power MOSFET and a low RDS(ON) MOSFET gate driver. The gate driver runs in an optimized dual-frequency mode, delivering high efficiency while maintaining a low noise level. The device can also be used without any external components such as inductors, capacitors, and ESRs. In addition, the device features a protection architecture and battery temperature monitoring.
-
Application Field
The TPS51206DSQT is designed to work in highly space-constrained applications such as handheld electronic devices, wearable applications, interactive industrial products, and consumer portable devices. With its wide range of programmable features such as input voltage range, output voltage range, charging current limit and temperature threshold, the device is suitable for smart phones, tablets, ultra-mobile devices, and other portable consumer electronics.
-
Working Principle
The device includes an integrated synchronous buck converter with a clock, a low RDS(ON) MOSFET gate driver, and a protection IC. It is designed to provide an efficient power solution from 4.5V up to 26.5V DC input voltage. The device takes multiple steps to ensure the safety of the system such as an integrated-current monitoring circuit and thermal shutdown protection. The device monitors the current at the battery to ensure that the discharging current does not exceed the programmable limit.
The device also has an integrated power switch that takes into consideration the voltage drop across the MOSFET and ensures that the output voltage is not exceeding the safe battery voltage. The device is programmable to limit the mode of the charger current based on the battery temperature or the battery chemistry. The device supports low current trickle charging below 100mA, pre-charge current, and constant current charging.
