Products

Category Name 1 Microcontroller
Product URL 1 Arm Cortex-M4|Kinetis KE1xF 32-bit 5V MCUs | NXP 
Product Description 1 The KE18F is a highly reliable 5 V MCU with a serial communication interface for industry applications. The integrated DSP along with the clock interfaces are the perfect choice for Air Conditioner motor control. This can be controlled using the 4 FlexTimers which offers up to 32 standard channels for PWM signal generation. The KE18F also has a 12-bit ADC with up to 16-channel input per module up to 1Msps and 3 high-speed analog comparators with internal 8-bit DAC.
Product link 2 Scalable Entry Level 32-bit Microcontroller (MCU) based on Arm® Cortex®-M0 Cores | NXP 
Product Description 2 The LPC11D00 is a low-cost 32-bit MCU, and it is designed for 8/16-bit microcontroller operations. This MCU is an Ultra-low power consumption for longer battery life that can be used with an LCD driver for remote control purposes.

 

Category Name 2 DC/DC Converter
Product URL 1 https://www.nxp.com/products/power-management/pmics/dc-to-dc-solutions/3.0-mhz-500-ma-dc-to-dc-boost...
Product Description 1 The PCA9410 power converter is the perfect fit for providing a 5V MCU enough power to correctly controlling with a Zigbee transceiver and a Liquid Crystal Display (LCD). All of this is powered with 1.5 V batteries.

 

Category Name 3 Temperature Sensor
Product URL 1 LM75B: Digital Temperature Sensor | NXP 
Product Description 1 The LM75B sensor can be configured to store programmable overtemperature shutdown and hysteresis limits to communicate them via the i2c-bus. This makes the LM75B the best solution to configure a temperature threshold and work with the air conditioner system.

 

Category Name 4 AC/DC Converter
Product URL 1 TEA172x | NXP 
Product Description 1 The TEA172X enables power engineers to design a reliable, cost-effective and efficient adapter supplies with low no-load power consumption. These features result in the TEA172X needing a minimum number of external components.

 

Category Name 5 LED Driver
Product URL 1 PCA9955BTW | NXP 
Product Description 1

The PCA9955B operates with a supply voltage range of 3 V to 5.5 V and the constant current sink LED outputs to allow up to 20 V for the LED supply. The

PCA9955B is the best option for individual PWM controller for up to 16 LED drivers for different LED states.

 

Category Name 6 Transceiver
Product URL 1 QN908x: Ultra-Low-Power Bluetooth Low Energy System on Chip (SoC) Solution | NXP 
Product Description 1 The QN908x is the perfect BLE solution for human-interface devices for its high-performance and highly integrated capabilities all this supported in a well-known secure protocol. The QN908x small dimensions and low component count reduces overall system size and cost for the end product.
Product URL 2 IEEE802.15.4 wireless microcontroller with 64 kB Flash, 8 kB RAM | NXP 
Product Description 2 The JN5161 is an ultra-low-power, high-performance wireless MCU supporting ZigBee Green Power. The JN51561 has a 128-bit AES security processor and a MAC accelerator that fits perfect in every smart-home solution, the low component count and low-cost BOM minimizes the production cost.

 

Category Name 7 Motor Driver
Product URL 1 Fm+ I2C-bus advanced stepper motor controller | NXP 
Product Description 1 The PCA9629A provides highly flexible control of stepper motor, off-load bus master/micro and significantly reduces I²C-bus traffic. This is very helpful in this case because there might be at least six i2c slaves connected to the same bus. The PCA9629A provides the logic control required to drive a four-phase stepper motors.
Product URL 2 GD3000 |3-phase Brushless Motor Pre-Driver | NXP 
Product Description 2 The GD3000 gate driver is controlled by a PWM signal created from the KE18F, it operates off of a single power supply with a wide range from 6V to 60V with 75V transient protection. The GD3000 has protection against reverse charge injection from CGD and CGS of external FETs, This feature is required to protect the whole control system.
