| Overview |
| The KTF809/810 Microprocessor Reset Circuits are low-power supervisory devices used to monitor power supplies. They perform
a single function: asserting a reset signal whenever the VCC supply voltage drops below
a preset value and keeping it asserted until
VCC has risen above the preset threshold for
a minimum period of time. |

| Features |
- Precision monitoring of 3V, 3.3V, and 5V supply voltages
- Minimum 140ms reset pulse width
- KTF809 - active-low output RSTB
- KTF810 - active-high output RST
- Low supply current – 7uA typical
- Guaranteed RESET assertion down to VCC=1.0V
