Alpha and Omega Semiconductor has released a 7A 23V USB Type-C protection and reverse-blocking switch IC. Dubbed AOZ1377DI, is can be used in both Sink and Source applications and it “offers features that significantly reduce voltage drop and power loss compared to back-to-back p-channel devices”, promises the company. Instead it uses a pair of internal drain-to-drain n-channel mosfets, whose gates ...
Nexperia has unveiled analogue switches that can work with control logic from 1.8 to 5V, regardless of supplies between 1.5 and 5.5V. There are two versions: NMUX1308, an 8:1 analogue multiplexer/demultiplexer which is compatible with, but more capable than, existing 4851 and 4051 analogue switches, and the NMUX1309 dual 4:1 analogue mux/demux which can replace 4852 and 4052 devices. All ...
Texas Instruments has announced a 220V (or ±110V) analogue switch with 16 channel of single-throw switching. It has logic-level (1.8 to 5V) control inputs, with thresholds set by the separate 1.7 to 5.5V logic supply, and needs at least 40V across its switch supply pins (0V and +40V, or ±20V, for example) to operate. Absolute max for the controlled signal ...
Omron has an excellent application note on mechanical microswitches, subtitled: ‘Let’s prolong switch life by preventing failures!‘ Hundreds of photos back up information on the causes of failure and techniques for preventing those failures. It is the sort of detail that makes the heart sing*, in a world dominated by ‘marketing-led’ information-deprived drivel. Hats off to Omron *spot the lover ...
CUI Devices has introduced dozens of illuminated tactile push button switches, in packages as small as 3.4 x 3.4 x 1.5mm. Colours span blue, green, red, red-blue, red-green, white and yellow, and there are actuator heights from 0.35 to 6.3mm, operating forces from 160 to 300gf, and lives up to 100,000 cycles. “These illuminated tactile switches carry surface mount or ...
Cherry has announced quieter operation amongst other up-grades to its long-running MX series of keyboard switches, with the introduction of MX2A types. At the same time, it revealed a keyboard, Xtrfy K5V2, built with the switches. The original gold cross-point contacts are retained and changes are largely details, with, for example. a move from cylindrical spring to an barrel spring to ...
Rohm has developed Hall-based magnetic detectors for vehicle use. BD5310xG-CZ types are momentary (dubbed ‘unipolar’): turning on above a fixed south pole magnetic flux density and turning off below the same threshold (with a small amount of hysteresis) BD5410xG-CZ types are latching: turning on above a fixed south pole flux density, then remaining on until an equal north pole flux ...
Moxa has introduced families of Ethernet switches for industrial environments. Spread across EDS-2000 and EDS-4000, they are being stocked in the UK by Impulse Embedded. “The core difference between ranges is their manageability: EDS-4000 switches are managed, which provides a higher level of control, security and optimisation,” according to Impulse, “EDS-2000 switches are unmanaged, which means that these function out-of-the-box, ...
Texas Instruments is previewing a 50V quad-channel single-pole analogue switch with a wide voltage range, low on-resistance and consistent on-resistance with signal amplitude. Called TMUX7612 and made on a CMOS process, it will run on single rails between 4.5 and 50V, dual rails from ±4.5 to ±25V, and asymmetric rails – the company gave 37.5Vdd and -12.5Vss as an example, ...
Nexperia has introduced its first 5V load switch IC, which operates across 2.5 – 5.5V with 110mA to 2.5A current limiting. The 2 x 2mm NPS4053, as it will be know, is optimised use in portable devices such as notebook computers, desktops and docking stations, and automotive infotainment systems – it is UL 62368 recognised and there is an AEC-Q100 ...
