Description

The MAX6820UT+T is a supervision component that belongs to the category of supervisors. MAX6819/MAX6820 devices are power-supply sequence controllers for dual-voltage microprocessors (μPs) and multivoltage systems. These small power-supply sequencers improve system reliability and control local component voltage sequencing when system power-on/power-off characteristics cannot be guaranteed (supplies come from a multivoltage system bus, silver box, or must be sequenced in different modes for components on the same board).

Specifications and features

The MAX6820UT+T component comes with the following features:

• Adjustable Primary Supply Voltage Monitor that monitors down to 0.62V
• Internal Charge Pump to Enhance External Secondary Supply n-Channel MOSFET Switch
• Delay from Primary Supply Good to Secondary Supply Enabled: Factory Fixed 200ms (MAX6819), Capacitor-Adjustable (MAX6820)
• Logic Driven ENABLE Input (MAX6819)
• Immune to Short Voltage Transients
• Few External Components
• -40°C to +125°C Operating Temperature Range
• Small 6-Pin SOT23 Package

Application Scenarios
