ELM76xxxxxxxxC
CMOS Voltage detector with delay function
■General description
ELM76xxxxxxxxC is CMOS voltage detector IC with delay function; external capacitor is unnecessary
for the delay time circuit. There are 4 types of delay time selection of ELM76 series: Typ.50ms, Typ.150ms,
Typ.250ms, Typ.500ms, and ELM76 series can also be made as semi-custom ICs within the range of 30ms
to 500ms by 10ms step. There are two output styles of ELM76 series: N-ch open-drain and CMOS output. In
addition, two output logic modes are available; RESET and RESET. The output level is high for RESET mode
and low for RESET mode when VDD is lower than detection voltage. The standard detection voltages are 1.6V,
2.5V, 2.7V, 3.0V, 4.0V and 5.5V and ELM76 series can also be made as semi-custom ICs within 1.6 to 5.5V by
0.1V step.
■Features
Detection voltage range
Low current consumption
Accuracy of detection voltage
Delay time after Vdd recovery
Hysteresis voltage

Re-understanding of analog ground and digital ground
In order to achieve good anti-interference, we often see ground splitting wiring on PCB boards. However, not all digital circuits and analog circuits must be split on the ground plane. Because this sp...

Problems with CRect and RECT
If I assign a CRect object to a RECT object, will there be any problems? For example, if a function parameter is of type RECT, but a CRect object is passed in as a parameter, will there be any problem...

【MicroPython】MicroPython mini board has arrived
I received a call from the courier today. I guessed that MicroPython had arrived, but it didn't turn out! 1. The packaging is anti-static, which is very considerate2. In addition to the small board, i...

I'm touched. It's great to have a video tutorial.
Yesterday I watched MSP430, the step-by-step video operation. Very detailed. It turns out that there are many things I don't understand about stm32. After watching the msp430 video tutorial. I underst...

The higher the frequency of electromagnetic waves, the farther they can be transmitted.
I've heard people say before that the higher the frequency, the greater the attenuation; recently I saw that "the higher the frequency of electromagnetic waves, the longer the transmission distance". ...
