4. S-1701 Series K/L/M types
Explanation for Each Type
The S-1701 Series A/B/C types provide a regulator block standby mode realized by an ON/OFF function that is active
high. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes
flows.
The SENSE pin is connected to the VIN pin in the internal circuit of the detector block, so the voltage applied to the
VIN pin is monitored and a reset signal is output from the VDOUT pin. The built-in counter timer allows selection of the
release delay time from three settings (A: No delay (60 μs), B: 50 ms, C: 100 ms).
The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be
taken concerning VIN pin input impedance
The S-1701 Series D/E/F types provide a regulator block standby mode realized by an ON/OFF function that is active
high. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes
flows.
The SENSE pin is connected to the VOUT pin, which is an output of the regulator, in the internal circuit of the detector
block, so the output voltage of the regulator (V
The built-in counter timer allows selection of the release delay time from three settings (D: No delay (60 μs), E: 50 ms,
F: 100 ms).
The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be
taken concerning the VIN pin input impedance
The S-1701 Series G/H/J types provide a regulator block standby mode realized by an ON/OFF function that is active
low. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes
flows.
The SENSE pin is connected to the VIN pin in the internal circuit of the detector block, so the voltage applied to the
VIN pin is monitored and a reset signal is output from the VDOUT pin. The built-in counter timer allows selection of the
release delay time from three settings (G: No delay (60 μs), H: 50 ms, J: 100 ms).

The S-1701 Series K/L/M types provide a regulator block standby mode realized by an ON/OFF function that is active
