Choose the Right Buck-Boost for Your IoT Tracker
NB-IoT and LoRa devices must operate in the field for several years powered only by small batteries. This type of operation requires careful selection of each block for minimum power consumption. The buck-boost regulator must operate efficiently over a wide output current range from tens of microamps to hundreds of milliamps. The MAX77827 buck-boost converter, with its high efficiency, smooth transition, low quiescent current and small size, provides an ideal power solution for NB-IoT and LoRa tracking applications.

Why Fast Time-to-Market Calls for Flexible EV Battery Management Systems

 

Why Fast Time-to-Market Calls for Flexible EV Battery Management Systems
The design of a smart sensor for electric vehicle batteries poses mechanical and electrical challenges. The MAX17853 is a flexible data-acquisition system for the management of high-voltage and low-voltage automotive battery modules. It allows for a flexible battery configuration that saves cost, time to qualification and time to market. With this solution, the voltage across each battery cell is measured with high accuracy for reporting and balancing, and the busbars are monitored for fault detection.

Choose the Proper PMIC to Boost Your Optical Sensor SNR

 

Choose the Proper PMIC to Boost Your Optical Sensor SNR
Boost converters are typically used to step up the battery voltage in portable and wearable devices. However, they exhibit behavior that can negatively impact the signal-to-noise ratio (SNR) in optical sensing applications. In this design solution, we explain why this happens and then present a new type of power management using a PMIC that features a boost converter specifically designed to maximize SNR in optical sensing applications.

Provide a Safe Power Path from the Car Battery to Remote Cameras

 

Provide a Safe Power Path from the Car Battery to Remote Cameras
Transmission of power and data on long coaxial cable bundles requires protection from various short-circuit modes (STG, STB). Remote cameras are small and require space- and power-efficient solutions. The MAX20039 buck-boost converter is an effective supply for power-over-coax. The MAX20087 quad power camera pro­tector is a compact, efficient protection IC. The dual MAX20019 cascade buck converter configuration delivers high efficiency in a small space. This triplet of ADAS ICs effectively provides power and protection to the path from the car battery to the remote cameras.
