ISL88001IH29Z-T7A

Supervisors Overview

The ISL88001IH29Z-T7A is a single-channel voltage supervisory circuit manufactured by Renesas Electronics. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 2.925 V. The device provides an active low reset signal with a minimum reset timeout of 140 ms. It utilizes a push-pull output configuration and is housed in a SC-70 (SOT-323) package. The component supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single input voltage channel for under-voltage conditions
• Generates an active low reset signal upon threshold detection
• Features a push-pull output stage for robust drive capability
• Includes a fixed minimum reset delay timer for system stability

Supervisors Applications

• Industrial control systems requiring power monitoring
• Embedded electronics needing simple reset supervision
• Portable devices utilizing low-voltage power rails

Supervisors Procurement Notes

Verify the specific suffix 'IH29Z' to confirm the 2.925 V threshold and SC-70 package variant. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check current availability as this product may be subject to discontinuation notices. Ensure the active low reset polarity matches the target microcontroller or logic interface requirements.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a push-pull output is required. The 2.925 V threshold suits applications monitoring 3.3 V or similar logic rails. Consider the 140 ms reset delay for timing-sensitive designs. Compare against the ISL88002 series if open-drain outputs or manual reset functionality are needed instead.

Supervisors Part Context

This part belongs to the ISL88001 family of voltage supervisors. It shares the SC-70 footprint with other variants but differs in threshold voltage and output type. The 'IH' prefix typically denotes the specific threshold and package combination within the Renesas portfolio. It serves as a fundamental power management IC for ensuring reliable system startup and operation.

Supervisors FAQ

What is the reset output polarity?

The reset output is active low, meaning it drives low when the monitored voltage falls below the threshold.

Does this device include a watchdog timer?

No, the ISL88001IH29Z-T7A is a simple reset supervisor and does not include a built-in watchdog timer function.
