bq2026-Based Circuit Module

The bq2026-based circuit module is ideal for programming the 1.5K-bit EPROM and the STATUS bytes of

the bq2026 IC. The circuit module includes a SOT23 single socket, a bq2026 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 bq2026 IC and a pullup

resistor is required.
