Test Summary
www.ti.com
Decrease the voltage of LOAD#2 slowly to approximately 3.5 V for Note 001 and 10.5 V for Note 002.
Measure
→
I(J2(VBAT)) = 2 A ±200 mA.
Observe
→
D1 (/STAT) ON.
2.7.5
OVP - Input Overvoltage Protection
Increase the voltage of PS#1 to 9 V for Note 001 or 20 V for Note 002.
Measure
→
I(J1(VIN)) = 0 A ±200 mA.
Observe
→
D1 (/STAT) BLINK.
2.7.6
DPM - Input Current Regulation
Connect the output of the Load#1 in series with a current meter (multimeter) to J2 (SYS, PGND). Ensure
that a voltage meter is connected across J2 (SYS, PGND). Resume other status as in

Turn on the power of Load#1. Set the load current to 0.5 A. Increase the load current until I(J1(VIN)) = 3
A.
A.
Observe
→
I(J2(VBAT)) decreases from 3 A to 0 A and I(J1(VIN)) keeps 3 A unchanged.
2.7.7
Test Complete
Turn off the power supply, and remove all connections from the unit under test (UUT).
