The KID65783AP chip is an 8-channel driver for controlling fluorescent displays, relays, lamps, etc.We send a signal up to 2 Volts to the input of one of the eight drivers, and load the output to a high-voltage lamp and another load with a voltage of up to 50 Volts, the current in the load is up to 500 mA.
Here are the main characteristics of the chip:
- Power supply up to 50 Volts
Output current 500mA
Temperature from -40 to +85 degrees
Input signal from 0.8 to 2 Volts
As you can see, there are protective diodes at the input of each driver, and the output is made of a composite transistor.Such a chip is often found on washing machine control boards.
Here is a diagram of the application of this driver to control the indicators in the clock on the attiny2313 microcontroller
