Maxim Integrated MAX822LUS T
- Part Number:
- MAX822LUS T
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3268883-MAX822LUS T
- Description:
- IC MONITOR VOLT MPU SOT143-4
- Datasheet:
- MAX822LUS T
Description
The MAX821/MAX822 microprocessor (μP) supervisory circuits monitor power supplies in μP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered or 3V-powered circuits. The MAX821/MAX822 also provide a power-on reset timeout delay that is pin selectable to 1ms (max), 20ms (min), or 100ms (min).
These devices perform a single function: they assert a reset signal whenever the VCC supply voltage falls below a preset threshold, and they keep reset asserted for the pin-selected reset timeout delay after VCC has risen above the reset threshold. The only difference between the two devices is that the MAX821 has an active-low RESET output (which is guaranteed to be in the correct state for VCC down to 1V), while the MAX822 has an active-high RESET output. The reset comparator is designed to ignore fast transients on VCC. Reset thresholds suitable for operation with a variety of supply voltages are available.
Low supply current makes the MAX821/MAX822 ideal for use in portable equipment. These devices come in a 4-pin SOT143 package.
