Automotive battery input protection reference design
Automotive battery power supply lines are prone to transients while running the system. Typical protections required are overvoltage, overload, reverse polarity, and jump start. During the life of a car, the alternator may be replaced with a non-OEM part.
Selecting operational amplifiers for HEV/EV powertrain systems
Texas Instruments' presentation will focus on the voltage and current monitoring solutions within HEV/EV system – specifically on overcoming the challenges of high voltages and maintaining an isolation barrier. Afterwards, they will discuss specific op amp parameters to consider for monitoring within the on-board charger (OBC), battery management system (BMS), DC/DC converter, and inverter end equipments.
Power supply design features digital controllers for cloud computing
Renesas Electronics has announced two new PMBus compliant, fully digital DC/DC controllers that provide single output point-of-load (POL) conversions for FPGAs, DSPs, ASICs, network processors and general purpose system rails. The ISL68300 with integrated MOSFET drivers and ISL68301 with PWM output simplify designing power supplies for data centre, wired and wireless communications, and factory automation equipment.
PMICs drive optimised power for ADAS functions
With a series of power-management ICs (PMICs) from Maxim Integrated Products, designers can optimise power for automotive advanced driver-assistance systems (ADAS) functions to achieve high performance, small size, efficiency, and electrical protection. ADAS functions, many of which are now mandatory or will be soon, increase vehicle safety and enhance the driving experience.
High power radial combiner designed for upgrade programme
Link Microtek has designed and produced a compact high power 9-way radial combiner specifically for BAE Systems as part of a programme to upgrade customers’ S-band radar transmitters by replacing their magnetrons with multiple Solid-State Power Amplifiers (SSPAs).
