Max. Min. Fig. 4 VOT output circuit (1) It is recommended to insert 5kΩ or more (5.1kΩ is recommended) pull down resistor for getting linear output characteristics at low temperature below room temperature. When the pull down resistor is inserted between VOT and VNC(control GND), the extra circuit current, which is calculated approximately by VOT output voltage divided by pull down resistance, flows as LVIC circuit current continuously. In the case of using VOT for detecting high temperature over room temperature only, it is unnecessary to insert the pull down resistor. (2) In the case of using VOT with low voltage controller like 3.3V MCU, VOT output might exceed control supply voltage 3.3V when temperature rises excessively. If system uses low voltage controller, it is recommended to insert a clamp Di between control supply of the controller and VOT output for preventing over voltage destruction. (3) In the case of not using VOT, leave VOT output NC (No Connection). Refer the application note for Super Mini DIPIPM Ver.5 series about the usage of VOT.
