Nexperia Introduces New Analog Switches Simplifying Design and Enhancing System Safety
The renowned semiconductor firm Nexperia has unveiled its latest line of 4- and 8-channel analog switches, tailored to effectively manage and safeguard 1.8 V electronics. Incorporated within this new multiplexer lineup are both AEC-Q100-compliant models aimed at the automotive market and generic variants apt for a wide spectrum of uses, such as sensor oversight and fault isolation, sophisticated computing in businesses, and household apparatuses.
Traditional design approaches often necessitate auxiliary voltage translators adjacent to analog switches due to incompatible control circuit voltage levels. In contrast, Nexperia's NMUX1308 and NMUX1309 switches come with control pins that function autonomously from their power supply voltage scope. This design innovation removes the requisite for extra level-shifting components, hence optimizing PCB real estate and lessening expenditure.
Forethought to system integrity has been a key focus for Nexperia, as these switches boast advanced characteristics that augment overall system robustness. The fail-safe logic feature empowers control pins to get bias in the absence of system power and maintain the bias post power-down. This eradicates the need for logistical power sequencing between the analog switch and the system microcontroller unit (MCU). Simultaneously, the power-off protection attribute allows for the biasing of analog pins outside of system power-up times and continuation after system shutdown. Such features abolish power sequencing constraints linked with the analog switch, the power rails sustaining analog signals, and ADC circuits down the signal path, averting supply rail back-powering through any analog switch pin.
