DC2161A-A

DC2161A-A is a demonstration board for LTC4231IMS-1 micropower hot swap controller with latch-off. Included on the board are input overvoltage and reverse voltage protection, input voltage dividers for UV and OV detection, an output voltage LED, jumpers to disable UV/OV, manual and remote enable control, and quiescent current measurement. There are turrets provided to monitor input voltage, output voltage, output status, quiescent current, several ground connections, timer pin and control the ON pin. Input, output and return voltages are provided on banana jacks.
