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 (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: 70µs (voltage detector), 1.5ms, 30ms, 210ms, and 1.68s. Reset thresholds suitable for operation with a variety of supply voltages are available. The PT7M6832/PT7M6835/PT7M6838 have a push- pull active-low reset output (RESET). The PT7M6833/ PT7M6836/PT7M6839 have a push-pull active-high reset output (RESET) and the PT7M 6834/ PT7M 6837/ PT7M 6840 have an open-drain active-low reset output (RESET). The open-drain active-low reset output requires a pull-up resistor that can be connected to a voltage higher than VCC. The PT7M6835/PT7M6836/PT7M6837 feature a debounced manual reset input (MR), while the PT7M6838/PT7M6839/PT7M6840 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 7.5µA makes the PT7M6832– PT7M6840 ideal for use in portable equipment. These devices are available in 3-pin SOT23 or 4-pin SOT143 packages.
