Gate driver offers programmable control and monitoring for automotive applications
The L99H92 automotive gate driver from STMicroelectronics provides an SPI port for programming and diagnostics, a charge pump, protective features, and two additional current-sense amplifiers for system monitoring. Containing two high-side and two low-side drivers, the L99H92 can control a single H bridge powering one bidirectional DC motor or two half bridges for two unidirectional […]
Resistors provide improved reliability for automotive and industrial applications
Many types of electronic products across a variety of market segments require higher reliability components. Automotive grade resistors offer increased reliability and improved performance without the high cost and limited availability of components procured to established reliability military specifications. For those applications that also require a defined pulse withstanding the options become limited. Stackpole’s RPCA […]
High-voltage DC caps operate to 105°C
TDK Corporation presents a new series of EPCOS power capacitors for DC link applications designed for an operating temperature of up to +105 °C. The components with the ordering code B25695E can operate at rated DC voltages from 700 V to 1300 V (voltage derating necessary from +85 °C). The ESR ranges from 1.0 mΩ […]

High-capacity, 100 V automotive MLCCs in miniatures sizes for 48 V architectures
TDK Corporation has expanded its CGA series of multilayer ceramic capacitors (MLCCs) to 2.2μF in 2012 size (2.0 x 1.25 x 1.25mm – L x W x T) and 4.7μF in 3216 size (3.2 x 1.6 x 1.6 mm – L x W x T), with the industry’s highest capacitance*, as 100V products for automotive […]
100 V Trench Schottky diodes boost efficiency in high-frequency power converters
STMicroelectronics has introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies. Raising power-converter operating frequency, encouraged by the minimal switching losses of technologies like wide-bandgap semiconductors, allows designers to set new benchmarks in power density. However, at elevated frequencies, the energy losses in conventional planar diodes, including […]
Zonal automotive power distribution can dramatically improve efficiency, weight, and cost: part 3
If something can’t go on, it won’t; supplying the automobile’s voracious electrical demands from a 12-V battery is an example of this reality. If you haven’t already, check out Part 1 and Part 2 of this discussion. Under the zonal architecture, many legacy loads will still be supported by a 12-V battery or its functional […]
