MPQ6400 Low Quiescent Current Programmable-Delay Supervisory Circuit AEC-Q100 Qualified The Future of Analog IC Technology DESCRIPTION FEATURES The MPQ6400 family is the microprocessor (P) Guaranteed Industrial/Automotive Temp supervisory circuit which can monitor and Range Limits provide reset function for system voltages from Fixed Threshold Voltages for Standard 0.4V. When either the SENSE voltage falls Voltage Rails From 0.9V to 5V and below its threshold (V ) or the voltage of IT Adjustable Voltage From 0.4V are Available MR manual reset ( ) is pulled to a logic low, the Low Quiescent Current: 1.6 A Typ RESET signal will be asserted. The reset Power-On Reset Generator with Adjustable voltage can be factory-set for standard voltage Delay Time: 2.1ms to 10s rails from 0.9V to 5V, while the MPQ6400DG- High Threshold Accuracy: 1% Typ MR 01 reset voltage is adjustable with an external Manual Reset ( ) Input MR RESET resistor divider. When SENSE voltage and Open-Drain Output RESET exceed their thresholds, is driven to a Immune to Short Negative SENSE Voltage logic high after a user-programmable delay time. Guaranteed Reset Valid to V =0.8V CC 22mm QFN The MPQ6400 has a very low quiescent current AEC-Q100 Qualified of 1.6 A typically, which makes it ideal suitable for battery-powered applications. It provides a APPLICATIONS precision reference to achieve 1% threshold Advanced Driver Assistance System (ADAS) accuracy. The reset delay time can be selected by a capacitor which is connected between Camera Monitor Systems C and GND, allowing the user to select any DELAY Sensor Fusion Systems delay time from 2.1ms to 10s. 380ms delay time Portable/Battery-Powered Products is selected by connecting the C pin to V , DELAY CC HEV/EV while 24ms delay time by leaving the C pin DELAY MCU/DSP/FPGA/ASIC Applications float. MPQ6400 is available in 2mm2mm 6-pin All MPS parts are lead-free, halogen-free, and adhere to the RoHS QFN package. directive.
