LTC1728ES5-5#TRPBF

Supervisors Overview

The LTC1728ES5-5#TRPBF is a triple power supply monitor integrated circuit manufactured by Analog Devices Inc. It operates within an ambient temperature range of -40°C to +85°C and utilizes a TSOT-23-5 surface-mount package. The device features three independent voltage monitoring channels with open-drain or open-collector outputs. Two thresholds are fixed at 1.683V and 2.805V, while the third channel offers adjustable threshold settings. The component provides a minimum reset timeout of 140ms and supports low-active reset signals for system supervision.

Supervisors Feature Summary

• Triple-channel voltage monitoring capability with two fixed thresholds and one adjustable threshold
• Open-drain or open-collector output configuration for flexible logic interfacing
• Low-voltage operation with defined reset timeout characteristics

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• System reset generation for microprocessors and FPGAs
• Voltage monitoring in portable electronic devices

Supervisors Procurement Notes

Verify the exact suffix #TRPBF against official Analog Devices documentation to confirm lead-free status and tape-and-reel packaging specifications. Confirm that the ES5 variant matches the required thermal performance and pinout for the target PCB layout. Cross-reference the specific part number with current manufacturer availability lists as distribution status may vary.

Supervisors Selection Notes

Select this component when a compact solution is required for supervising multiple voltage rails simultaneously. The combination of fixed and adjustable thresholds allows customization for specific logic levels without external resistors. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range for reliable reset timing.

Supervisors Part Context

This part belongs to the LTC1728 series of multi-supply monitors from Analog Devices. It is designed to replace discrete comparator-based supervision circuits, reducing board space and design complexity. The TSOT-23-5 package offers a small footprint suitable for dense consumer and industrial electronics layouts.
