PMICs open up options for IoT battery types

They PMICs allow developers to choose the optimal battery type and chemistries for an application, from IoT sensors, asset tags, smart meters, home and building automation, security to health and wellness products.

According to the company, the PMICs save time in choosing the right device for low power IoT designs.

The family of PMICs includes low-voltage DC/DC converters and regulators and a flexible mechanism to manage the power rails in a system design. They have flexible I/O voltage and a wide input voltage range (0.8 to 5.5V) to support an array of batteries. They also have wide output voltages to support a variety of peripherals, microcontrollers and radios.

The PMICs enable buck and boost voltage conversion as well as combined boost and buck (boost bootstrap) supporting low-voltage, high-current rails for IoT products requiring coin cell batteries and higher transmit power (up to 20 dBm).

Multiple output power rails allow an IoT device to be powered by one low-cost PMIC, saving board real estate. It also simplifies software/hardware design, says the company.

The PMICs have quiescent current as low as 150 nA to reduce sleep current and enhance battery life. They also support coulomb counting which offers vital information for battery life estimation and preventive maintenance.

The PMICs are in a 3.0 x 3.0mm QFN20 package and are sampling now. Three development boards are also available: the SLWRB4179B radio board and two PMIC evaluation boards. The company’s Simplicity Studio offers energy profiler and network analyser tools, wireless stacks and reference designs, is also available and is free of charge.
