Generally speaking, the requirements of the working environment of intelligent inspection robots and intelligent sorting robots are very stringent. For the power supply for IC chips to provide these signals, high speed and high precision are often indispensable factors.

Requirement 1: Test of quiescent current

Under a certain voltage, let the IC be in a no-load and no-oscillation state. Connect one end of the ammeter to the positive terminal of the power supply and the other end to the VDD pin of the IC. The reading of the ammeter is the quiescent current of the IC.

Requirement 2: Test of drive current

Under a certain voltage, replace the load of the IC with an adjustable resistor to allow the IC to work normally. When the output port has an output, adjust the resistance of the adjustable resistor to make the level of the IC output meet the test requirements.

For the above test requirements, according to the voltage specifications and accuracy requirements, a suitable DC power supply is recommended, such as IT6400 bipolar power supply; IT6100 high-speed high-precision power supply; among them, IT6400 bipolar power supply has a high accuracy of na level, which is used as a power supply, and Can test quiescent current.

In summary: IC chip testing is often inseparable from a high-precision and high-speed power supply. As the world’s leading provider of power supply testing solutions, ITECH plays an important role in the performance testing of the robot’s internal energy supply system and power devices. , Whether it is used as an enabling power supply for testing robot sensor circuits or IC chip components, or ITS9500 power supply test system testing the power supply conditions of robot power supply circuits, or testing requirements of various power levels, ITECH can rely on High-quality and high-precision test solutions escort engineers’ R&D and production, and truly realize “china made”.
