Battery Charger Timer
The ELM380 is an 8 pin integrated circuit that is
used to provide very long time interval outputs. It is
typically used for enabling the charge circuit in
Nickel Cadmium battery chargers, but can be easily
adapted for many other applications.
An express ‘one button’ mode is provided on
chip specifically for rechargeable battery circuits. In
this mode, pressing the start button once initiates a
user selectable 8 or 14 hour timing interval, after
which the circuit shuts off. If one prefers, pressing
that same button multiple times will allow for user
programmable intervals of from 2 to 77 hours.
The circuit requires a 60Hz full-wave rectified
signal for its operation. This 120Hz time base is
used for all of the timekeeping functions, providing
good long term stability and low cost.
Interfacing to the ELM380 is simplified by the
provision of internal pull-up resistors so that the
mechanical switches can be directly connected
without additional components, or simply not used,
depending on the application.
