TPS3124J18 采用 5/SOT23 封装且具有看门狗的单通道 (1.5V) SVS
TPS3124J18 描述
The TPS312x family of ultralow voltage processor supervisory circuits provides circuit initialization and timing supervision, primarily for DSP and processor-based systems.
During power-on, RESET is asserted when the supply voltage (VDD) becomes higher than 0.75 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET output active as long as VDD remains below the threshold voltage (VIT). An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time, td = 180 ms, starts after VDD has risen above the threshold voltage (VIT).
When the supply voltage drops below the threshold voltage (VIT), the output becomes active (low) again. No external components are required.
