Test Procedure for the NCP4305 Put-In Board 2 x SO8FL DN05071 02/03/2015 Figure 1: Test Setup The following steps describe the test procedure for all these boards: Required Equipment: DC voltage source (e.g. STATRON 2229) ………………………...…… 1pc DC Amp-Meter (e.g. KEITHLEY 2000)………………………………… 1pc Function generator (e.g. AFG3252) ……………………………………... 1pc 2 channel oscilloscope …………………………………………………...1pc Test Procedure: 1. Connect the test setup as shown in figure 1. 2. Apply an supply voltage, VCC = 12 V 3. Apply pulse from generator (pulse, f = 100 kHz, DC = 50%, VLOW = -1 V, VHIGH = 4 V, output impedance = high Z) 4. Check that ICC = 20 mA, waveforms look like in figure 2 (DRV pulses may oscillate between 470 ns and 5 µs) 5. 6. 7. 8. Set DC to 13% Check that ICC = 1.6 mA, waveforms look like in figure 3 (no DRV pulses) Turn off VCC End of the test Figure 2: VCC = 12 V, f = 100 kHz, DC = 50%, VLOW = -1 V, VHIGH = 4 V Figure 3: VCC = 12 V, f = 100 kHz, DC = 13%, VLOW = -1 V, VHIGH = 4 V
