Table 1 Pin Description
* I : Input, O : Output, I/O: Bi-directional, OD: Open-Drain I/O, PI: Power Supply Bypass
AD1 (No.16) pin and PROC (No.17) pin are input pins. WDC (No.18) pin is open-drain pin with pull-up resistance.
However, these pins operate as bi-directional pins. No.16pin and No.17pin connect with V
resistance. No.18pin do not connect or connect with V
VREGO (No.12) pin is a built-in power supply bypass pin. Connect low-ESR capacitor of 4.7uF and 0.01uF in parallel
between VSS (No.11) pin. A built-in power supply is used only for NJU26125 operation. Be not short-circuited of this pin.
Do not take out the current, and connect other power supplies.
Do not open the terminals without pull-up resistance and pull-down resistance.
