e-peas launches PMIC series enabling energy harvesting and 5 V charging
e-peas, a leader in ultra-low-power energy harvesting and power management solutions, has introduced a new series of Power Management ICs (PMICs) designed to enhance design flexibility for original equipment manufacturers (OEMs). This series aims to eliminate the reliance on disposable batteries in a wide range of devices, including remote controls, keyboards, mice, consumer and IT peripherals, IoT sensors, and smart home products.
The core innovation of this PMIC series lies in its common pinout across all three devices: the AEM11920, AEM11921, and SPM10140. This allows OEMs to develop a single PCB layout that can accommodate different charging configurations. Designers can seamlessly switch between variants that support energy harvesting (e.g., from an embedded PV cell) alongside 5V charging, or those that are exclusively 5V charging, by simply changing the PMIC and making minimal component adjustments.
This approach significantly reduces design complexity, cost, and time, enabling manufacturers to offer both premium, energy-harvesting products and more cost-effective 5V-charged options from a unified design platform. The series also addresses growing environmental concerns by promoting the use of rechargeable devices and energy harvesting alternatives, thereby reducing the volume of disposable batteries ending up in landfills.
