Microprocessor Reset circuits
General Description
This system reset IC, developed using the CMOS pr-
ocess, has a built-in delay function. Super low consu-
mption current of 1.0µ A typ. has been achieved throu-
gh use of the CMOS process. Also, detection voltage is
high precision detection of 2%.
Applications
• Monitoring processor, ASIC, or FPGA core and I/O
voltages
• PDAs, hand-held PCs
• Embedded controllers
• Telecommunications systems
• Power supplies
• Wireless / Cellular systems
• Networking hardware
Features
• Under-voltage monitor
• Super low consumption current(1.0uA typ)
• High precision detection voltage(2%)
• Operating range(0.7 - 10V)
• Wide operating temperature range(-30 to +85^°C)
• Power-on reset generation (150ms Typ)
• Choice of threshold voltages (contact Kingbor regarding
availability)
• Active-low reset output
• Rejects brief input transients
• Industry standard package and pinout
• 4-pin SC-82AB package
