These devices combine three popular functions; Power-on  
Reset Control, Watchdog Timer and Supply Voltage  
Supervision. This combination lowers system cost, reduces  
board space requirements and increases reliability.  
Features  
• Selectable watchdog timer  
- Select 200ms, 600ms, 1.4s, off  
• Low VCC detection and reset assertion  
Applying power to the device activates the power-on reset  
circuit which holds RESET/RESET active for a period of  
time. This allows the power supply and oscillator to stabilize  
before the processor can execute code.  
- Five standard reset threshold voltages nominal 4.62V,  
4.38V, 2.92V, 2.68V, 1.75V  
- Adjust low VCC reset threshold voltage using special  
programming sequence  
- Reset signal valid to VCC = 1V  
The Watchdog Timer provides an independent protection  
mechanism for microcontrollers. When the microcontroller  
fails to restart a timer within a selectable time out interval,  
the device activates the RESET/RESET signal. The user  
selects the interval from three preset values. Once selected,  
the interval does not change, even after cycling the power.  
• Low power CMOS  
- 12µA typical standby current, watchdog on  
- 800nA typical standby current watchdog off  
- 3mA active current  
• 400kHz I2C interface  
The device’s low VCC detection circuitry protects the user’s  
system from low voltage conditions, resetting the system  
when VCC falls below the minimum VCC trip point.  
RESET/RESET is asserted until VCC returns to proper  
operating level and stabilizes. Five industry standard VTRIP  
thresholds are available; however, Intersil’s unique circuits  
allow the threshold to be reprogrammed to meet custom  
requirements, or to fine-tune the threshold for applications  
requiring higher precision.  
• 1.8V to 5.5V power supply operation  
• Available packages  
- 8 Ld SOIC  
- 8 Ld MSOP  
• Pb-free available (RoHS compliant)
