ISL88001IH31Z-TK

Supervisors Overview

The ISL88001IH31Z-TK is a low-power voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input voltage within a range of 1.8 V to 5.5 V. The device features an active-low, push-pull reset output with a fixed threshold voltage of 3.07 V. Specific thresholds include an undervoltage limit of 3.038 V and an overvoltage limit of 3.112 V. The reset delay time is 190 ms, and the operating supply current is 350 nA. Accuracy is specified at 1.2%. It operates between -40°C and +85°C in an SOT-23 package.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage and over-voltage conditions
• Provides an active-low, push-pull reset signal without manual reset capability
• Operates with ultra-low supply current suitable for battery-powered applications

Supervisors Applications

• Portable electronic devices requiring voltage supervision
• Battery-operated systems needing low quiescent current monitoring
• Industrial control circuits utilizing standard voltage rails

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold and package selection. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Check for end-of-life notices or production change notifications that may affect long-term availability. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

Supervisors Selection Notes

Select this component when a single-channel supervisor with push-pull output is required. Compare threshold accuracy and reset delay times against system timing requirements. Evaluate the SOT-23 package constraints against board space limitations. Consider the operating temperature range suitability for the intended environment.
