Operation
The RT4823 combines built-in power transistors,
synchronous rectification, and low supply current, and it
provides a compact solution for system using advanced
Li-Ion battery chemistries.
In boost mode, output voltage regulation is guaranteed
to maximum load current of 1.5A. Quiescent current in
Shutdown mode is less than 1
A, which maximizes the
battery life.
Power-On Reset
If input voltage is lower than POR, the internal digital
and analog circuit are disabled. If input voltage is higher
than POR, the Boost converter behavior is shown as
follows :
1. IC Digital circuit will be activated.
2. Internal register will be loaded in default value.
3. Boost
converter
will
enter
free-running
mode
(detailed information is shown in free-running mode
section).
4. If VOUT > 2.2V (or VIN > 2.2V), Boost converter will
enter closed loop control and load in E-fuse value to
the internal register.
