Figure 3-5, Figure 3-6, and Figure 3-7 show the OPA607 current-sensing waveforms with 100 kHz, 500 kHz, and 1 MHz, respectively. The 220-ns phase delay, intentionally introduced to filter high-frequency noise, can be optimized with system requisitions.
With the OPA607 amplifier and TLV3502 comparator, overcurrent protection for MOSFET response is validated as in Figure 3-8 shows the negative direction OCP response time and Figure 3-9 shows the positive direction OCP response time.
