4 BQ2407x Optional Functions

The BQ2407x family of devices have optional features on pin 15 of each device. These functions on pin 15 of the device allows the devices to be used in a variety of applications.

Part Number Optional Function Use
BQ24072 TD Charge termination can be disabled by pulling the TD pin high. Charge termination is enabled when TD is connected to VSS. Note the TD is internally pulled down with a 285 kΩ resistor
BQ24073
BQ24074 ITERM The ITERM pin can be used to adjust the charge termination current by connecting a 0Ω to 15 kΩ resistor. If ITERM is left unconnected, the termination current is set to 10% of the fast charge current.
BQ24075 SYSOFF The FET between BAT and the Output can be turned off by setting SYSOFF high. Setting SYSOFF low put the device in normal operation. SYSOFF is internally pulled up to BAT.
