Diodes

Diodes has introduced a 64Gtransfer/s PAM-4 intra-equipment range extender for PCIe 6.0 data busses, that is backwards-compatible with PCIe 5.0, 4.0 and 3.0. PI3EQX64904 is a four-differential-channel linear device with equalisation including tunable low and high-frequency and high-frequency zeros. “It optimises performance over a variety of physical media by reducing inter-symbol interference, correcting for known channel losses at the transmitter ...

AL8866Q is an AEC-Q100 (Grade 1) qualified dc-dc converter controller aimed at automotive front lights such has headlamps. In needs an external n-channel power mosfet, and can implement buck, boost, buck-boost or SEPIC (single-ended primary-inductance converter, pictured) topologies. Operation is from 4.7 to 85V, covering 12V, 24V and 48V battery power rails. Analogue and PWM dimming are possible via a ...

Diodes has introduced a 12-channel constant-current LED driver arranged as four channels of RGB. AL58221 has open-drain outputs that can sink up to 60mA and withstand 24V. Maximum red green and blue currents are set with three resistors, then the individual channels are digitally-modulated to set their brightness. To reduce flicker, adaptive pulse density modulation is used, with diodes claiming ...

It seems to be Ideal Diode Week at Electronics Weekly (here and here) as Diodes is also promoting one, this time an ideal diode that can cope with ±65V on its input and drops only 20mV when conducting. The automotive-compliant AP74700Q operates down to 3.2V (or 3.9V at start-up) to allow for cold cranking of a vehicle engine. Inside, a ...

The AH3712 is a latching Hall-effect magnetic sensor, protected for automotive electrical conditions, in a choice of SC59, SOT23 or SIP-3 packaging. The single output is switched ‘on’ with a magnetic pole above a certain flux density, and then switched ‘off’ when exposed to the opposite pole of the same flux density magnitude. There are three parts: AH3712: south pole ...

Now in its sixth year of awards, EW BrightSparks sees Electronics Weekly highlight and celebrate some of the brightest and most talented young engineers in the UK today. Here, in our series on the latest EW BrightSparks of 2023, we profile Alex Jarvis, an Application Engineer at Diodes Incorporated. Achievements It was his manager at Diodes who nominated Alex, telling ...

Diodes is aiming at active matrix OLED panels with three-output power management dc-dc converter. Running from 2.9 to 4.8V, AL3565 produces: 4.6 to 5.0V (VPOS) with 0.5% accuracy at up to 500mA from a buck-boost converter -1.4 to -5.4V (VNEG) with 0.5% accuracy at up to 500mA from an inverting buck-boost converter 5.8 to 7.9V (AVDD) with 0.5% accuracy at ...

According to the judges, the AL5887 offers a number of benefits to customers and is a more sustainable choice than other LED drivers on the market. One judge in particular remarked on the ultra-low shutdown low power saving mode. Shortlist * Diodes – AL5887 dual digital interface, multi-channel LED driver for RGB and single colour, solid state lighting * Indie ...

Diodes has is aiming at automotive LED strings with a boost and SEPIC (single-ended primary-inductance converter) controller, that can also be wired as a voltage regulator. Called AL8853AQ, it is qualified to AEC-Q100 and implements current-mode and fixed-frequency (400khz) PWM control. Slope-compensation is included to prevent sub-harmonic oscillation at duty cycles >50%. The IC requires an external n-channel power switching ...

Aiming at industrial and automotive applications, Diodes has introduced a portfolio of Hall-effect sensors for measuring linear and angular speed and direction. Called AH39xxQ, “they also have a 40V absolute maximum rating, enabling them to safely handle 40V load dumps”, according to the company. “Additionally, -18V of reverse voltage protection guards against incorrect battery connections. For added robustness, the ESD ...
