Test Setup
6.3.3
Start-Up No Receiver
Do not place any receiver on PWR607 for this test.
Turn on power supply and observe that:
1. Input voltage at J1 is 4.9 V to 5.1 V and current is less than 100 mA with a high-to-low fluctuation or
toggling.
2. On UUT PWR607, Power On green LED D1 is ON
3. On UUT PWR607 LED D4, D5 and D6 are OFF
4.
Using current probe, monitor input current and observe digital pin will occur every 5 s for 70
ms.
6.3.4
Receiver In Place – No Load
Place HPA764 on PWR607 above the TX Coil, load should be set to 10 k
Ω
or 0 mA.
Observe that:
1. On HPA764, LED D1 is ON
2. On HPA764, voltage at TP7 should be 4.9 V to 5.1 V
3. On HPA764, voltage at TP12 should be 7.0 V to 7.5 V, voltage will fluctuate.
4. On UUT PWR607 during power transfer (HPA764 D1 ON):
(a) LED D6, flashing Green
(b) Input current should be less than 300 mA
6.3.5
Receiver In Place – 1.0-A Load
With the HPA764 in place on the PWR607, above TX Coil set output load current to 950 mA to 1050 mA.
Input voltage at UUT J1 should be 4.9 V to 5.1 V, adjust input supply if necessary.
Observe that:
1. On HPA764 LED D1 is ON
2. On HPA764, voltage at TP7 should be 4.9 V to 5.1 V
3. On HPA764, voltage at TP12 should be 5.1 V to 5.3 V
4. On UUT, PWR607 LED D6 Flashing Green
5. On UUT, PWR607 input current should be less than 1700 mA
