TPS2042BDR General Description

Texas Instruments' TPS2042BDR stands out as a precise voltage supervisor and reset generator integrated circuit. Boasting a precision voltage reference with an exceptional accuracy of ±1.5%, this IC is engineered to monitor the system's supply voltage effectively. In the event of a voltage dip below the pre-set threshold, the TPS2042BDR swiftly generates a reset signal featuring an active-low output and a pulse duration of 20ms, perfect for rebooting microcontrollers and digital logic circuits. Operating within a broad voltage range of 2.7V to 6V, this device operates efficiently, consuming minimal quiescent current, making it an optimal choice for applications reliant on battery power. Additionally, the TPS2042BDR comes in a compact 8-pin SOIC package, facilitating easy integration into diverse electronic systems, ensuring seamless voltage supervision and reset generation capabilities
