2. Connect a 0-V DC power supply capable of 250 mA minimum between the "BAT-" and "BAT+" terminals and
adjust to approximately 45 V.
3. Connect a meter to a VSS test point and monitor the COUT or DOUT test points, or the corresponding
signals at J4 terminals 4 or 5.
4. Observe that both the COUT (J4 pin 4) and DOUT (J4 pin 5) are low, approximately 0 V.
5. Remove the cell simulator shunt for cell 2, J6 pins 17 and 18.
6. Observe the COUT and DOUT signals are low.
7. Install the cell 2 cell simulator shunt at J6 pins 17 and 18.
8. Adjust the supply voltage to approximately 71 V. Observe the COUT transitions to approximately 7 V after 4
seconds. Confirm DOUT remains low if desired.
9. Adjust the supply voltage to approximately 31 V. Observe DOUT is approximately 7 V after 4 seconds as the
part transitions to UV mode. Observe COUT is low if desired.
10.Make other adjustments as desired for evaluation. See other sections of this user guide for details of
operation.
11. When complete with this quick start demonstration, turn off the power supply.
Refer to other sections of this user guide for additional details.
