A low-voltage supervisor IC for monitoring power supplies as low as 1.5V has been developed by Micrel Semiconductor an industry leader in power management integrated circuits. Available in Micrel's IttyBitty SOT23-5 packaging, the MIC2775 features a choice of factory-programmed voltage options and ultra-low quiescent current. The MIC2775 is available in a range of factory programmed voltage options to completely eliminate external components. The industry-standard package and pinout make it a drop-in upgrade for previous generations of supervisor ICs. The quiescent power supply current is a portable-friendly 3.5uA. Both an active-high and an active-low reset output are provided in addition to a manual reset input for a reset switch or for daisy-chaining onto existing power supervision circuitry.
These devices are manufactured using Micrel's proprietary BiCMOS process. Summary of features includes a 1.5V - 5.5V operating range, a choice of preprogrammed voltage options, generation of power-on reset pulse (140ms min.), a debounced manual reset input, both active-high and active-low reset outputs, an ultra-low supply current (3.5uA typical), rejection of brief input transients, Itty-Bitty SOT23-5 package and an industry-standard package/pinout.
