Host and Pushbutton Communication

The DA9072 features multiple digital pins for host and user communication, see Table 35, with

connections shown in Figure 27.

Table 35: Digital Pins for Host and Pushbutton Interface

Pin Name

Description

SCL / SDA

I2C interface

MODE

Mode control input

Used to enter Hi-Z mode and control charging

(Edge triggered for Hi-Z control; level triggered for charge control)

RIN_N

Pushbutton interface

Used to wake up from Ship mode and Hi-Z mode

Also used to generate a low-active reset pulse on ROUT_N

SYS_FLT

IRQ interrupt output flag

Also functions as a charging status indicator

PWR_FLT

Power input status flag

Can also be configured as a voltage shifted RIN_N output

ROUT_N

Host reset output which is controlled by RIN_N

Watchdog input
