ISL88011IH546Z-TK

Supervisors Overview

The ISL88011IH546Z-TK is a single-channel voltage supervisor IC from the Intersil (Renesas) ISL88011 family. It monitors one input voltage with a fixed threshold of 4.64V. The device features an open-drain and push-pull output configuration, supporting both active-high and active-low reset signals. It includes manual reset functionality and a typical reset delay time of 250 ms. The component operates within a supply voltage range up to 5.5 V and functions across a temperature range of -40°C to +85°C. It is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Combines open-drain and push-pull output stages for flexible interface compatibility
• Provides manual reset capability alongside automatic power-on reset functions
• Monitors a single voltage channel with a fixed threshold level

Supervisors Applications

• Portable equipment requiring low-voltage monitoring
• Battery-powered systems needing supervision
• General-purpose microprocessor reset circuits

Supervisors Procurement Notes

Verify the specific suffix 'H546' corresponds to the required 4.64V threshold during procurement. Confirm the 'TK' tape-and-reel packaging format matches assembly requirements. Ensure the source document identifies the manufacturer as Intersil or Renesas Electronics Corporation. Check for any end-of-life notices associated with this specific part number variant before finalizing orders.

Supervisors Selection Notes

Select this component when a single-channel supervisor with combined open-drain and push-pull outputs is required. The fixed 4.64V threshold suits applications where this specific voltage level must be monitored. Consider the SOT-23-5 package size for space-constrained designs. Verify that the 250 ms reset delay meets system timing constraints.

Supervisors Part Context

This part belongs to the ISL88011 through ISL88015 family of voltage supervisors. These devices integrate popular functions such as power-on reset and adjustable or fixed voltage monitoring. The family is designed for portable equipment and battery-operated systems, offering various output configurations and threshold options within a small footprint.

Supervisors Replacement Considerations

Other parts in the ISL88011 family may serve as substitutes if different thresholds or output types are acceptable. Verify pinout compatibility and electrical specifications before substitution. No direct public substitute part numbers are confirmed for this exact threshold and package combination.
