Electronic Speed Controller  [Auto-Layout Example]
The electronic speed controller (ESC) is an essential part of an electric propulsion system’s hardware. It acts like the brain of the system by telling the motor how fast to go based on data signals it receives from the throttle controller. For smaller applications like drones and RC vehicles, this controller has the name ‘ESC’, whereas for larger manufacturing applications it may be called an electronic control unit, inverter, or motor controller. #drone #motorController #PCA9685 #controller #motor #esc #referenceDesign #project #EFM8BB21F16G #MPU9250 #template

NCP176BMX330TCG
The Onsemi NCP176 CMOS Low Dropout (LDO) Regulator is designed for superior transient response and low voltage operation, providing a maximum output current of 500 mA. It operates with an input voltage range from 1.4 V to 5.5 V and offers an output voltage range from 0.7 V to 3.6 V in 0.1 V steps. Characterized by a typical quiescent current of 60 µA and a low dropout voltage of 130 mV at 500 mA with a 2.5 V output, the NCP176 ensures high output voltage accuracy of ±0.8% for outputs above 1.8 V. The regulator is stable with small 1 µF ceramic capacitors and includes features such as over-current protection, built-in soft start to suppress inrush current, thermal shutdown protection at 165℃, and an optional output discharge function available in the NCP176A variant. Packaged in a compact XDFN6 1.2 mm x 1.2 mm x 0.4 mm, this LDO regulator is ideal for battery-powered equipment, portable communication devices, and cameras.

TPS62130ARGTR
The TPS6213x series, manufactured by Texas Instruments, includes highly efficient, easy-to-use synchronous step-down DC-DC converters optimized for applications requiring high power density. These converters operate within a wide input voltage range from 3 V to 17 V and are capable of delivering up to 3 A of continuous output current. The series comprises multiple part numbers, namely TPS62130, TPS62130A, TPS62131, TPS62132, and TPS62133, each offering unique output configurations—adjustable outputs for TPS62130 and TPS62130A, and fixed outputs of 1.8 V, 3.3 V, and 5.0 V for TPS62131, TPS62132, and TPS62133 respectively. Key features of the TPS6213x series include the advanced DCS-Control™ topology for improved transient response and high output voltage accuracy, a programmable soft start, seamless transition to power save mode, and selectable operating frequency (either 1.25 MHz or 2.5 MHz). The device also encapsulates robust protection mechanisms such as short circuit and overtemperature protection. Housed in a compact 3-mm x 3-mm QFN-16 package, the IC includes additional functions like a power-good output and 100% duty cycle mode for low dropout conditions. With a highly integrated design that requires minimal external components, the TPS6213x series is ideal for step-down regulation in various applications including standard 12-V rail supplies, POL supplies, embedded systems, and portable devices.
