Improve automobile battery life with the right chemistry
by Theju Bernard, Intersil, a Renesas Company The automotive industry is quickly moving toward more electrification. The deployment of start-stop systems, emergency call (eCall) telematics, and hybrid vehicles is fueling the need for advanced battery management systems that not only charge the battery in a safe manner but also prolong its useful life. There are […]
Sync buck regulators step down inputs to just 0.6 V
Intersil, a subsidiary of Renesas Electronics Corporation (TSE: 6723), today introduced five synchronous buck regulators that step-down 12V rails to point-of load inputs as low as 0.6V for MCUs, FPGAs, memory and peripheral I/Os. The newest members of the ISL850xx family consist of the ISL85014, ISL85012, ISL85009, ISL85005A and ISL85005 buck regulators. They deliver 14A, […]
Avoiding mobile device brownouts
By Chuck Wong, Intersil, a Renesas Company With the ever-increasing performance of mobile application processors and GPUs, the need for a buck-boost regulator to stabilize the Li-ion battery supply-voltage terminals is becoming more and more important. Buck-boost regulators prevent brownout (a condition where power is briefly lost) by boosting the supply voltage during the notching […]
How to Protect Li-ion Battery Packs
by Ryan Roderick, Intersil Corporation Today’s Lithium-ion (Li-ion) batteries are seeing increasing use in a wide range of applications, including electric scooters, portable power tools, and plug-in hybrid electric vehicles. And designing protection circuitry to safeguard them has never been more important. The power FET is an essential safety function in a battery management system […]
Single-Chip USB-C buck-boost battery chargers support bidirectional power
Intersil Corporation today introduced two new USB-C™ buck-boost battery chargers that support bidirectional power delivery in ultrabooks, tablets, power banks and other mobile products. The single-chip ISL9238 and ISL9238A battery chargers replace competitive two-chip solutions to reduce customer bill of materials (BOM) costs by up to 40%. Both ICs employ Intersil’s patented R3™ modulation technology to […]
Six-Phase bidirectional dc/dc controller optimized for 12-48-V vehicle power systems
Intersil Corporation today announced it is shipping the industry’s first 6-phase bi-directional PWM controller designed to perform buck and boost power conversions between 12V and 48V automotive buses. A single automotive-grade ISL78226 delivers up to 3.75kW at greater than 95% conversion efficiency, and is able to interleave in a modular master/slave architecture to deliver higher power. […]
