I believe ti is no stranger to everyone. Texas Instruments (TI) is one of the largest semiconductor companies in the world. Always committed to providing innovative semiconductor technology to help customers develop the world’s most advanced electronic products. Analog, embedded processing and wireless technology continue to penetrate into all aspects of life, from digital communication and entertainment to medical services, automotive systems and a wide range of applications.

The lmp91300 we introduced this time is ti’s product.

Application analysis of inductive proximity sensor in chip manufacturing

The lmp91300 is a complete analog front end (AFE) optimized for industrial inductive proximity sensors. Lmp91300 directly converts RP of external LC storage tank to digital value.

Fully supports post manufacturing configuration and calibration. An external temperature sensor is used to digitally compensate the temperature dependence of the sensor. Lmp91300 provides programmable threshold, programmable temperature compensation and programmable oscillation frequency range. Due to its programmability, the lmp91300 can be used with a variety of external inductors, and its detection threshold can be adjusted to the required detection distance.

The internal voltage regulator allows the device to operate in the power supply range of 6.5V to 40V. The output can be programmed to drive external transistors in NPN or PNP mode.

The lmp91300 is packaged in 4mm x 5mm 24 terminal wqfn and 2.05mm x 2.67mm 20 terminal dsbga with an operating temperature range of – 40 ° C to + 125 ° C.

features

Post production configuration and calibration, programmable decision threshold, programmable hysteresis, flexible overload protection, digital temperature compensation, integrated LED driver, small size, support 4mm sensor (dsbga package), low power consumption, integrated voltage regulator, 3-wire function, support NPN and PNP modes, normally open (no) and normally closed (NC) support 16 bit resolution threshold setting

Friends who are familiar with sensors feel particularly familiar with these features.

Let’s take a look at the definition, that is, how to use it:

Of course, this chip alone is not enough. It also needs some peripheral hardware support

Well, can an inductive proximity switch sensor with modern technology be manufactured? Or when we have time, we can actually build one with this chip.
