New high-temperature linear voltage regular offers a low cost and reliable solution

13-05-2019 | Cissoid | Automotive Technologies

CISSOID offers the new CXT-STA4919, a new high-temperature, high-reliability, 50mA adjustable linear voltage regulator generating any regulated voltage in the range 3.3V to 28V from an input between 4.5V to 35V. The component operates reliably at junction temperatures from -55C to 175C. It is self-protected with a built-in current limiter and thermal protection. The regulator is offered in a PSOIC8 package with exposed pad for small PCB footprint and low thermal resistance.


“This product offers a low cost, small footprint and reliable solution for compact voltage regulators in ECU’s, motor drives modules and sensor interfaces located in harsh automotive thermal environments where thermal requirements are difficult to meet,” says Pierre Delatte, CISSOID CTO. “We see also demand in high power density converters and SiC gate drivers in EV and HEV” he added.


The company is also launching new automotive configurable logic gates, referenced as CXT-741GXX, rated from -55C to 175C and available in a small SOT-23-6 package. These configurable integrated products allow 13 logic functions including inverter, buffer, AND, NAND, OR, NOR, XOR, XNOR, MUX and D Flip-Flop. These new low power CMOS devices have a supply voltage range from 1.65V to 5.5V. Inputs feature Schmitt triggers for high immunity to slow-changing signals and can be driven with signals above the supply voltage.


“This new CXT product series shows CISSOID commitment in providing solutions for emissions reduction by enabling smart motor drives, harsh environments sensors and compact power converters for new electrical and hybrid vehicles,” says Dave Hutton, CISSOID CEO.
