EST.5198B
USB Charger Enhance IC
FUNCTION DESCRIPTION
1. The EST5198B is an USB dedicated charging port (DCP) controller. The built-in auto-detect function can
monitors the voltage of D+ and D- data lines. To provide the correct voltage level on the D+ and D- data lines
automatically, the compliant USB devices can be charged with the charging current as much as possible. That
can reduce the charging time when use the EST5198B as the controller in the USB charge feature kit.
2. MODE truth table

U1:
5198B
CAUTION:
When select the charge mode, please make sure the current ability of power source that can provide the desired
continue current. Any maximum continue charging current must not exceed the limited of the maximum current rating of
the power source, like wall adapter, vehicle USB charger, and other USB charger.
3. The EST5198B only control the voltage of D＋/ D－ lines on the USB port to support the
auto-detect charging procedure and does not control the USB power (VBUS) operation. The
remaining battery capacity in the compliant USB devices may affect the charging current. If the
remaining battery capacity is low, the charging current may be high. Conversely the charging
current may be low when the remaining battery capacity is high.
