Halo Microelectronics announced two new products that utilize switched capacitor architecture to deliver 98% efficiency DC-DC conversion, which outperforms traditional DC-DC converters by up to 10% efficiency. This higher efficiency significantly reduces the thermal dissipation in mobile devices such as smartphones, thus enabling more power to be delivered to the battery and resulting in a […]
USB BC 1.2-compliant battery charging detector incorporates host and client circuitry
Diodes Incorporated today announced the dual-role PI3USB9201 USB BC 1.2 detector, which incorporates both host and client circuitry, enabling designers to optimize the BoM size and cost of adding USB Type-C interface circuitry in devices such as laptops, tablets, smartphones, drones, and small home appliances. Unlike current market solutions that require devices dedicated to either […]

Energy efficient supercapacitor cell balancers include over-voltage protection
The precision dual-channel SABMBOVP2XX family of products automatically balances supercapacitors with the addition of over-voltage protection (OVP). The result is energy-efficient supercapacitor balancing, ideal for products that require low-loss energy power, leakage current regulation, and OVP. Supercapacitor cells typically operate at a nominal recommended working voltage. However, voltages that exceed the maximum rating for a […]
Buck converters switch at 4 MHz to power mobile processors
A new power management product family consists of four sub-PMICs that offer best-in-class transient response and in-circuit digital programmability, in a smaller form factor than current market solutions. The new product family of buck converters, which consists of the DA9217, DA9220, DA9121 and the DA9122, represents Dialog’s first sub-PMIC family with a 4-MHz switching frequency […]
Battery charger delivers termination current of 20 mA
Texas Instruments introduced a new switching battery charger integrated circuit (IC) that supports a termination current of 20 mA. Compared to competing devices, which typically support a termination current higher than 60 mA, TI’s BQ25619 enables 7% higher battery capacity and longer run time. The BQ25619 charger also delivers three-in-one boost converter integration and ultra-fast […]

Standard amplifier functions in HEV/EV battery management systems
by Sanjeev Manadhar, Texas Instruments Hybrid electric vehicles (HEVs) and electric vehicles (EVs) are popular because they have low (to zero) emissions and fewer maintenance requirements while offering better efficiency and drive performance. New HEV/EV companies are emerging, while existing automakers are investing more in HEV/EV to compete for market share. The heart of the […]
Want a new perspective on battery management? Buy a plug-in EV.
One facet of EV ownership: Thinking of your daily commute power consumption as equivalent to the sunlight hitting 20 ft2 of your lawn. Rudye McGlothlin, Silicon Labs Earlier this year I took my first step into the EV future by buying a plug-in hybrid electric vehicle (PHEV) – a Chevrolet Volt. A unique car in […]
