DC2472A

DC2472A is a battery stack simulator for LTC68xx demonstration board. The demonstration circuit 2472A provides a simple battery stack simulator for connection directly to most of Linear Technology’s LTC68xx “battery stack monitor” demo boards. Using the 5V from a USB charger, the DC2472 generates an isolated high voltage from 25V to 75V, applied to a resistor string generating 18 voltages taps. These taps provide a simulation of a string of series connected battery cells, each tap pair providing nominally the same virtual cell voltage. The input voltage to the resistor string is adjustable by an on-board potentiometer to furnish a divided output voltage in a range of about 1.5V-4.2V per cell to demonstrate operation at conditions comparable to a wide range of cell chemistries.

• Power up the DC2472A from the USB cable or bench supply
• DC2472A is a resistor-string voltage-divider ladder powered by a variable voltage
