The low power push-button controllers feature a selectable reset time delay to improve system stability.
Available in a 1.45 x 1 x 0.55mm SON package, they are suitable for space constrained portable applications such as pedometers, fitness bands, cell phones and tablets.
The dual channel TPS3420 and TPS3421 use a long input delay to provide the intended system reset and avoid reset from short push button or key presses.
According to TI, this reset configuration enables differentiation between software interrupts and hard system resets.
