DESCRIPTION
The SC89601S is a 1.5MHz highly integrated switch-mode
buck charger for 1 cell Li-ion battery applications and NVDC
system power path management, which separate the system
load and charge current, also the system can power up with
deep depletion battery. System can get the power from VBUS,
VBAT or both. It supports 3.9-13.5V input voltage, up to 3A
charging current and provide battery charge management
functions including trickle charge, constant current charge,
constant voltage charge, charge termination, auto recharge
and charging status indication.
The SC89601S supports flexible charge current option, the
user can program the current and all others charger spec by
I2C. With the charger management function, the IC can be
used to charge 1 cell Li-ion battery.
The SC89601S supports USB OTG with up to 1.2A output with
PFM/PWM mode. Meanwhile, the SC89601S supports USB
BC1.2 and non-standard adapters.
The SC89601S supports input current and voltage limit, input
under voltage and over voltage protections, internal cycle by
cycle current limit, battery short circuit protection, and output
over voltage protection. It also offers charging safety timer and
over temperature protection to ensure safety under different
abnormal conditions.
The SC89601S integrated all MOSFETs, current sensing, loop
compensation and I2C interface. The SC89601S is available in
QFN(24)-4*4 package.
