MAX6832, MAX6833, MAX6834, MAX6835, MAX6836, MAX6837, MAX6838, MAX6839, MAX6840 Ultra-Low-Voltage SC70 Voltage Detectors And �P Reset Circuits

The MAX6832 MAX6833 MAX6834 MAX6835 MAX6836 MAX6837 MAX6838 MAX6839 MAX6840 are Microprocessor (P) Supervisory Circuits used to monitor low-voltage power supplies in P and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +1.2V to +1.8V powered circuits. These devices assert a reset signal whenever the VCC supply voltage declines below a preset threshold or whenever manual reset (active-low MR) is asserted. Reset remains asserted for a fixed timeout delay after VCC has risen above the reset threshold or when manual reset is deasserted. Five different timeout periods are available: 70s (voltage detector), 1.5ms, 30ms, 210ms, and 1.68s. Reset thresholds suitable for operation with a variety of supply voltages are available. The MAX6832 MAX6835 MAX6838 have a push-pull active-low reset output (active-low RESET). The MAX6833 MAX6836 MAX6839 have a push-pull active-high reset output (RESET) and the MAX6834 MAX6837 MAX6840 have an open-drain active-low reset output (active-low RESET). The open-drain active-low reset output requires a pullup resistor that CAN be connected to a voltage higher than VCC. The MAX6835 MAX6836 MAX6837 feature a debounced manual reset input (active-low MR), while the MAX6838 MAX6839 MAX6840 provide a RESET-IN input allowing the user to externally adjust the reset threshold. The reset Comparator is designed to ignore fast transients on VCC. Low supply current of 7.5A makes the MAX6832 MAX6833 MAX6834 MAX6835 MAX6836 MAX6837 MAX6838 MAX6839 MAX6840 ideal for use in portable equipment. These devices are available in 3- and 4-pin SC70 packages. By Maxim Integrated Products
