Supervisor IC for 1.8V Rails
The Texas Instruments TPS3831G18DQNT is a simple reset/power-on reset supervisor that monitors a single voltage rail with a 1.67V threshold, ideal for 1.8V supply supervision in embedded systems. It asserts an active-low, push-pull reset output for a minimum of 120ms after the monitored voltage rises above the threshold, ensuring the processor or FPGA starts from a known state.
Housed in a 4-X2SON (1x1 mm) supplier device package, this supervisor is a surface-mount component. The small footprint suits space-constrained designs like portable instruments or compact control modules.
