ISL88001IH29Z-TK

Supervisors Overview

The ISL88001IH29Z-TK is a single-channel voltage supervisor IC from Renesas Electronics Corporation, designed for precise power supply monitoring. It features an extremely low quiescent current of 160nA and operates within a temperature range of -40°C to 85°C. The device provides a fixed threshold voltage of 2.925V with an active-low reset output utilizing a push-pull, totem pole configuration. A minimum reset timeout of 140ms ensures reliable system recovery. This component is housed in a compact SOT-23-3 package, making it suitable for space-constrained applications requiring efficient voltage supervision.

Supervisors Procurement Notes

Verify the specific suffix 'IH29Z-TK' to confirm the 2.925V threshold and SOT-23-3 packaging. Ensure compatibility with your system's voltage levels and reset timing requirements. Check for any recent Product Change Notices (PCN) regarding datasheet updates or manufacturing changes. Confirm RoHS compliance status if required for your region. Cross-reference with official Renesas documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component when ultra-low standby current is critical for battery-operated applications. The fixed 2.925V threshold suits systems monitoring 3.3V rails or similar voltages. Consider the SOT-23-3 package size for PCB layout constraints. Evaluate the 140ms minimum reset timeout against your microcontroller's startup time. Compare with other Renesas supervisors offering different thresholds or packages if voltage requirements vary.
