Rohm has created a set of six current sense amplifiers with AEC-Q100 qualification for automotive use. They work with external shunt resistors, and there are two basic types: one (BD1423xFVJ-C) that can sense across the common-mode range of -14 to +80V and runs from 2.7 to 18V, and the other (BD1422xG-C) that can sense across -14 to +40V and runs ...

STMicroelectronics has made an eight-channel low-side driver for vehicles with extra functional safety hardware that “eases system-level ISO 26262 certification up to ASIL-B”, said the company. The nominal ratings of L9800, as it will be known, are: 12V power rail and 260mA per output. L9800 outputs can drive resistive, capacitive or inductive loads like relays, solenoids and LEDs,” said ST. ...

February is definitely the month for automotive high and low-side drivers, proved beyond doubt as Diodes has just followed Rohm, Toshiba and STMicroelectronics with its contribution: a protected 4A (25A pulsed) high-side switch. Called ZXMS81045SPQ, it operates across 5 – 28V (41V abs max) and responds to both 5V and 3.3V logic inputs. Packaging is SO-8 with an exposed heat sinking ...

Rohm has released one and two channel 40V low-side switches with AEC-Q100 qualification for automotive and industrial use. BV1LExxxEFJ-C (single-channel, 4.9 x 6 x 1mm HTSOP-J8) and BM2LExxxFJ-C (dual-channel, 4.9 x 6 x 1.65mm SOP-J8) “are suitable for systems such as car body control, engine and transmission control units, LED lighting modules or industrial programmable logic controllers”, according to the ...

Toshiba has created octal high-side and low-side protected load drivers in SSOP30 packaging (9.7 x 7.6 x 1.2mm, 0.65mm pitch). The company is promoting them as smaller alternatives to SSOP24 packaged drivers like TPD2005F and TPD2007F. The new parts use the company’s latest analogue process which is BiCD – combining bipolar, CMOS and DMOS elements. The high-side switching TPD2015FN (right) ...

Infineon is aiming at power factor correction and synchronous rectification with a 24V 10A dual channel low-side gate driver for mosfets and IGBTs. Called 2ED24427N01F, it provides symmetrical source and sink capability with 450mΩ (max) source and sink on-resistance per channel and 55ns propagation delay. The package is a 5 x 6mm DSO-8 with a solder-down exposed power pad – Junction ...

Infineon has added slew-rate control to its Hitfet range of relay-replacing low-side switches. Aimed at automotive and industrial applications, and called Hitfet+, the devices also have enhanced diagnostics, digital status feedback and improved short-circuit robustness. “Depending on vehicle class, every car produced today has about 7-11 protected low-side power switches,” said Infineon automotive v-p Andreas Doll. “Infineon invented Hitfet protected ...
