1.3、Introduction
HB6298A is an integrated 1-cell/2-cell
Li-ion/Li polymer switch-mode charge management
device, targeted at a wide range of portable
applications. HB6298A offers integrated power FET,
high-accuracy current and voltage regulation,
charge preconditioning, charge status, and charge
termination, in a small TSSOP20 package. HB6298A
charges the battary in three phase: preconditioning,
constant current(CC), and constant voltage(CV).
The charge current is programmable with an
external resistor up to 1.5A. HB6298A features
cycle-by-cycle current limit, charge current
thermal foldback and short circuit protection to
guarantee safe operation. Additional features
include NTC thermistor interface to monitor
the battery temperature.
