Figure 2-2. QT2 Charger
QT2 is an 8pin MCU, although it is a small pin count MCU but it has all
the critical features that a MCU needed. It has two channels of powerful
timer, 4 ADC channels, maximum 6 I/Os. LVI, COP, external IRQ etc.
The four 4 8-bit ADC channel and the powerful timer which can be config
as PWM output make it suitable for working as a single cell Li-ion battery
charger controller. In this Li-ion battery charger reference desgin, the
design concept is to make the cost as low as possible but at the same
time maintain all the necessary battery charger function and
performance.
