Triple Voltage Monitor with Adjustable Power-On Reset and Undervoltage Monitoring Capability ISL88021IU8HEZ-TK
The ISL88021 and ISL88022 family of devices are customizable triple voltage-monitoring supervisors that assert a reset if any of the monitored voltages becomes non-compliant. They offer popular functions such as Power-On-Reset timing control with both RESET and span style="text-decorati on: overline"RESET/span outputs, Supply Voltage Supervision, both under or overvoltage detection, and Manual Reset assertion. By offering these features in a small 8 Ld MSOP package, the ISL88021 and ISL88022 can lower system cost, reduce board space requirements and increase the reliability of systems.brbr Applying a voltage to VsubDD/sub activates the Power-On-Reset circuit which holds span style="text-decorati on: overline"RESET/span low for an adjustable period of time. This allows the power supply and system oscillator to stabilize before the processor can execute code.brbr Low VsubDD/sub detection circuitry protects the user's system from low voltage conditions, resetting the system when VsubDD/sub falls below its minimum preset voltage threshold VTH1. Reset remains asserted until VsubDD/sub returns to its proper operating level and stabilizes. Two additional voltage monitoring inputs, V2MON (preset) and V3MON (adjustable), monitor other supplies to provide reliable system operation.brbr The ISL88021 V3MON input monitors for undervoltage (UV) conditions whereas the ISL88022 V3MON input allows monitoring for overvoltage (OV) conditions. The monitored voltage on V3MON on either device is compared via a resistor divider to a 600mV internal reference. Hence, any voltage more or less positive than this reference can be accurately monitored to meet specific system level requirements or to fine-tune the threshold for applications requiring higher precision.brbr These devices also let users
