Part Number : TPS3421EG
Function : Low-Power, Push-Button Controllers with Configurable Delay
Maker : Texas Instruments

Pinouts :
TPS3421EG datasheet

Description : DESCRIPTION
The TPS3420, TPS3421, and TPS3422 (TPS342x) are low-current, ultrasmall, push-button reset timers.

These devices use a long timing setup delay to provide the intended system reset, and avoid resets from short push-button closures or key presses. This
reset configuration also allows for differentiation between software interrupts and hard system resets.

FEATURES
• Very Small Package: 1.45-mm × 1-mm SON
• Operating Range: 1.6 V to 6.5 V
• Single (TPS3422) or Dual (TPS3420 and TPS3421) Push-Button Inputs
• Low Supply Current: 250 nA
• Two-State Logic, User-Selectable Input Delay:
– For Example: 7.5 s and 0 s
– Multiple Timing Options Available
• Fixed Timeout Pulse at RST (TPS3421 and TPS3422): 400 ms
– Other Timing Options Available on Request
• Active Low, Open-Drain Output
