| Ordering number : EN5719 Monolithic Linear IC LA5623M Combination System Reset IC Overview The LA5623M is a combination reset IC that provides two reset functions. The first, reset 1, detects the input voltage and applies a reset to the CPU system and other logic systems. The second, reset 2, detects the power supply voltage when the power is turned on or off, and applies a reset to the CPU system and other logic systems. This latter function allows the reset time to be adjusted from two external pins. Package Dimensions unit: mm 3032B-MFP8 [LA5623M] Features * Reset circuit (output 1) that detects the input voltage and provides a delay time of 200 s. * System reset circuit (output 2) that provides a switchable delay time of 25, 50, 100, or 200 ms. * Low operating limit voltage * Both reset 1 and reset 2 have hysteresis characteristics.
