Test Summary
Connect the meters, scope probes, output loads, shunt, and input power supply as listed in
and
set scope to 2 ms/div, single sequence positive trigger; CH1 set to 500 mV/div and CH2 to 2 V/div; DC
coupled on CH1 and CH2.
coupled on CH1 and CH2.
The circuit on this sheet is typically not part of the charger design.
This circuit generates the pulses to program the charge, which is normally done by the host. Use only one Shunt on
JP101 through JP113. Place shunt according to desired program pluses. The 100 numbered components are part of
the hardware for creating the programming pulses and are not typically part of an application.
