ISL88002IH29Z-T

Supervisors Overview

The ISL88002IH29Z-T is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input channel with a threshold voltage of 2.92 V and an accuracy of 1.2%. The device features an active low, open-drain reset output and a reset delay time of 190 ms. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical operating supply current of 350 nA. The component is housed in an SOT-23 package and supports surface mount installation. It functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides undervoltage supervision for a single monitored input channel
• Delivers an active low reset signal via an open-drain output configuration
• Operates with ultra-low power consumption suitable for battery-powered applications

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing voltage level monitoring
• Embedded circuits utilizing low-power supervisory logic

Supervisors Procurement Notes

Verify the specific suffix Z-T against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance and moisture sensitivity level requirements before integration. Check for end-of-life notices as this series may have discontinuation updates. Ensure the SOT-23 footprint matches the target PCB design constraints.

Supervisors Selection Notes

Select this component when a simple, low-cost voltage monitor is required for a single rail. The open-drain output allows flexibility in interfacing with various logic levels. Consider the 190 ms delay for system startup timing. Compare against other ISL88002 variants if different threshold voltages or package types like SC-70 are needed for space-constrained designs.
