SP809 / SP810
3 Pin Microprocessor Supervisor Circuit
ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
VCC .......................................................... -0.3V to 6.5V
RESET, RESET.................................... -0.3V to VCC+0.3V
Output Current (RESET, RESET) .............................20mA
Power Dissipation (TA=70°C) .............................. 320mW
Junction Temperature .......................................... 125°C
Storage Temperature .............................. -65°C to 150°C
OPERATING RATINGS
Input Voltage Range VCC ................................ 0.9V to 6V
Junction Temperature Range ..................... -40°C to 85°C
ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Temperature of TA = 25°C only; limits applying over the full
Operating Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test, design, or
statistical correlation. Typical values represent the most likely parametric norm at TA = 25°C, and are provided for reference
purposes only. Unless otherwise indicated, TA= 25°C.
