Micrel MIC2785
The MIC2785 is a micropower voltage monitor that • No external components provides under-voltage monitoring and manual reset • Monitors input voltage for under-voltage condition capability in a tiny 1.2mm x 1.2mm MLF® package. The • Separate inputs for supply (VDD) and monitor (VIN) MIC2785 provides a monitored voltage input (VIN) separate • +1.5% VIN threshold voltage accuracy from the supply input (VDD). This insures that the reset • Valid /RST state with VIN down to 0.0V (/RST) output maintains a valid output state when the voltage being monitored ramps up or down.| Part No. | MIC2785 |

GENERAL DESCRIPTION
FEATURES
The device● Valid /RST state with VDD down to 1.20V also includes a manual reset input (/MR). The /RST output
● Factory-programmed 1.62V reference is an active low push-pull output.
● Manual reset input (/MR) The under-voltage detector compares the VIN pin voltage
● Active low RESET (/RST) output against the factory-programmed threshold of 1.62V. The
● Ultra-low input current – 5µA total (VIN and VDD) reset output is asserted any time the input voltage drops below the programmed threshold voltage. A reset can be
● Rejects brief input transients generated at any time by asserting the manual reset input,
● -25°C to 85°C operating temperature range /MR. This reset output will remain active until the release
● RoHS lead-free compliant of /MR. The /MR input can also be used to daisy-chain the
● Available in tiny 6-pin 1.2mm x 1.2mm Thin MLF® MIC2785 onto existing power monitoring circuitry or other package supervisors. Hysteresis is included to prevent chattering due to noise.
