PST852A

MITSUMI System Reset IC PST85XX Series System Reset IC Monolithic IC PST85XX Series Outline This is a reset IC with In various CPU systems or other logic systems, when the time of a power supply injection and a power supply are severed for a moment, this IC detects supply voltage and applies reset to a system. PST85 has separated the detecting voltage monitor terminal (VS) and the VDD terminal. Even if monitor voltage VS falls, when an operating limit is reached for another power supply, an output does not become unfixed, and the power supply of IC can maintain low level. It is especially suitable for the power supply surveillance of the low power supply (1V system). Features 1. High Accuracy 2. Super low supply current 3. Operating-voltage range 4. Operating-temperature range 5. Detecting voltage rank 6. Output type Typ±0.8% (VTH=0.8~1.9V) Typ±0.5% (VTH=2.0~6.0V) Typ 0.35µA 0.70V~10V -40~+105°C 1.2V~6.0V (0.1Vstep) CMOS output (PST851) Open drain output (PST852) Packages SS...
