The charger status indicator in primary side, no
need any devices for indicating the charger status in
secondary side. The indicator integrated in
FT832DB can be adjustable by a resistor between
the pin Cable and gnd .FT832DB facilitates CC/CV
charger design by eliminating an opto-coupler and
TL431. Its highly integrated functions such as Under
Voltage Lockout (UVLO), Leading Edge Blanking
(LEB), Built-in Line Compensation, External Power
NPN Transistor offer the users a high efficiency and
low cost solution for charger applications.
Furthermore, FT832DB features fruitful protections
like OTP (Over Temperature Protection), OVP (Over
Voltage Protection), and Open Circuit Protection,
Short Circuit Protection to eliminate the external
protection circuits and provide reliable operation.
FT832DB is available in SOP8 packages.
