Description
The PT7M3808G family of microprocessor supervisoryandnbsp;circuits monitor system voltage from 0.4V to 5.0V, assertingandnbsp;an open-drain RESETsignal when the SENSE voltageandnbsp;drops below a preset threshold or when the manual resetandnbsp;(MR )pin drops to a logic low. The RESET outputandnbsp;remains low for the user-adjustable delay time after theandnbsp;SENSE voltage and manual reset ( MR )return above theandnbsp;respective thresholds.
The PT7M3808G series uses a precision reference to achieveandnbsp;0.5% threshold accuracy for VIT s3.3 V. The reset delayandnbsp;time can be set to 20ms by disconnecting the Cr pin, 300msandnbsp;by connecting the C+ pin to Vop using a resister, or can beandnbsp;user-adjusted between 1.25ms and 10s by connecting the Candnbsp;pin to an external capacitor. The PT7M3808 has a very lowandnbsp;typical quiescent current of 2.8uA so it is well-suited toandnbsp;battery-powered applications.It is available in a smallandnbsp;SOT23 and an ultra-small 2.0x2.0 TDFN package, and isandnbsp;fully specified over a temperature range of -40anddeg;C to +125anddeg;C.
