Bluetooth is a short-range wireless communication technology that enables data exchange between fixed devices and mobile devices.BLE (Bluetooh Low Energy) technology is a short-range, low-cost, interoperable wireless technology that uses many intelligent means to minimize power consumption.

The Senasic SNP739 series chip is the first domestically produced high-integration TPMS chip. Independently developed, it holds over 40 patent certifications. In October 2017, it passed the AEC-Q100 automotive-grade certification and entered mass production. Thanks to its low power consumption and high performance, it quickly gained market recognition and has been purchased by over a hundred customers, with cumulative sales reaching tens of millions

SNU511 can simultaneously interface with two resistive bridges. It supports digital compensation for offset, sensitivity, temperature drift, and non-linearity. Calibration coefficients and configuration data are stored in non-volatile memory (NVM), and it also supports overvoltage and reverse connection protection up to ±40V, making it more reliable in automotive applications.

SNP736 is a high-integration Bluetooth tire pressure monitoring chip with BLE transmission functionality. It features high integration, high precision, high reliability, compact size, and low power consumption, making it highly suitable for deployment in new automotive system architectures. It is also suitable for long-distance transmission or transmission scenarios with complex interference sources.

SNU501 is precisely such a chip capable of driving resistive bridge pressure sensors. This chip is used for measuring pressure and temperature. It collects pressure data through internal high-resolution ADC, temperature compensation, and pressure compensation, providing calibrated pressure data directly.

SNU301 is a chip designed to drive capacitive pressure sensors, used for pressure and temperature measurements. It features internal high-resolution ADC, temperature compensation, and pressure compensation, providing calibrated pressure data directly.

Senasic's BPS-SNP805 has come into being. By issuing early warning messages in advance, it helps prevent the loss of life and property caused by battery pack fires, providing strong safety protection for drivers and passengers.
