It provides both active-high and active-low reset outputs in a push-pull, totem-pole configuration, giving the designer flexibility to interface with either polarity of reset logic on the downstream processor or FPGA. Housed in a SOT-23-5 package, it is a compact, surface-mount part suited for space-constrained boards where a dedicated voltage supervisor is needed to ensure clean power-up and brown-out protection.
The reset threshold is 1.62 V, making it suitable for monitoring a 1.8 V supply rail or other low-voltage core supplies.
The TPS3125J18DBVT provides both active-high and active-low reset outputs, giving the designer the option to connect to either polarity of reset input on the supervised device.
The reset timeout is a minimum of 100 ms, ensuring the system is held in reset long enough for the supply and oscillator to stabilise after a fault condition clears.
