How to achieve fast frequency hopping
Frequency hopping describes a method in which communication systems rapidly change their operating frequency for purposes specific to their application. Applications such as communications, radar and electronic warfare use frequency hopping in order to avoid interference or detection, or to detect cloaked signals.

38V, 10A H-bridge motor driver with integrated current sensing
The DRV8873 device is an integrated driver IC for driving a brushed DC motor in industrial applications. Two logic inputs control the H-bridge driver, which consists of four N-channel MOSFETs that drive motors bi-directionally with up to 10A peak current. The device operates from a single power supply and supports a wide input supply range from 4.5-38V.
Eight questions about monitoring in hybrids and EVs
Collectively, we’re engaged in a worldwide effort to reimagine automotive and reduce emissions, whether it’s helping carmakers offload combustion engines or transition to fully electric fleets. Electrification has proven to be the most adaptable tool for reducing emissions, but as voltage increases within vehicles, so does the significance of monitoring and protection subsystems.
Why Low Quiescent Current Matters for Longer Battery Life
Battery life is getting increased scrutiny as our devices continue to shrink but are still expected to deliver more functionality and performance than ever before. Effectively extending battery life in future devices will require mastery of low quiescent current. This paper examines the role of low quiescent current in delivering the battery life essential for today’s (and tomorrow’s) connected devices. Read more here.

Trends and Topologies for Automotive Rear Lighting Systems
In the early 1900s, driving at night was precarious. Lit by kerosene lamps, drivers announced their maneuvers with hand signals and shouts while employing guesswork to predict the actions of the other cars on the road. With fewer cars moving at slower speeds and dodging the occasional horse and wagon, they got by alright, but we’ve come a long way.
Low-noise transformer driver for isolated power supplies
The SN6505x-Q1 is a low-noise, low-EMI push-pull transformer driver, specifically designed for small form factor, isolated power supplies. It drives low-profile, center-tapped transformers from a 2.25V to 5V DC power supply.
Compact bias supply for IGBT/SiC gate drivers
This reference design is a 4.2W, single-channel, automotive 12V battery input flyback bias supply for IGBT/SiC isolated gate drivers. The supply accepts a wide input range of 4.5 to 65V DC. The output is configurable as +15V, -8V or +20V, -4V at loads up to 180 mA for driving the IGBT/SiC MOSFET power modules.
Automotive camera design with MIPI CSI-2 interface
This camera module reference design addresses the need for small cameras in automotive systems by combining a 2-megapixel imager with a 4-Gbps serliazier. Additionally, it provides power and voltage supervision from a single Power Management IC (PMIC).
