bq2022A-Based Circuit Module
The bq2022A-based circuit module is ideal for programming the 1 K-bit EPROM and the STATUS bytes of
the bq2022A IC. The circuit module includes a 3-pin SOT23 dual socket, a bq2022A IC, a Zener diode for
host protection during EPROM programming, and a programming circuit that generates a 12-V pulse when
used with a power supply and a control signal. In a typical application, only the bq2022A IC and a pullup
resistor is required.
