7. Application Information

A voltage pulse of 5 V for 2 μs in 10 kHz can be select as the set/reset signal. The pulse voltage, pulse width

and duty cycle can be adjusted in a certain range. A typical drive circuit is shown in Figure 7.

Figure 7. Set/reset drive circuit of AMR2302

The circuit will generate 5 V set/reset pulses, as illustrated in figure 8.

Figure 8. Set/reset voltage pulses waveform

When set-only or reset-only pulse is applied, the set- and reset- pulse is switchable by reversing the

set/reset input.
