TPS3124J18DBVR

Supervisors Overview

The TPS3124J18DBVR is a voltage supervisory circuit manufactured by Texas Instruments, designed for ultra-low voltage processor applications. It operates within a supply voltage range of 750 mV to 3.3 V and features a threshold voltage of 1.62 V with an overvoltage threshold of 1.68 V. The device provides active high and active low push-pull outputs with a reset delay time of 180 ms. It includes a watchdog timer but lacks manual reset and battery backup switching capabilities. The component draws a working supply current of 14 uA and functions reliably across a temperature range of -40°C to +85°C in an SOT-23-5 package.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides dual active high and active low push-pull output configurations
• Operates with ultra-low quiescent current consumption
• Supports single-input voltage supervision without manual reset

Supervisors Applications

• Ultra-low voltage processor systems
• Portable electronic devices requiring power management
• Battery-powered equipment with voltage monitoring needs

Supervisors Procurement Notes

Verify the specific suffix J18 corresponds to the required 1.62 V threshold and 180 ms delay parameters. Confirm the SOT-23-5 package compatibility with your PCB footprint. Ensure the operating temperature range meets your environmental requirements. Check for RoHS compliance status if mandated by your project specifications. Validate that the push-pull output type matches your downstream logic interface.

Supervisors Selection Notes

Select this component when a single-supply supervisor with integrated watchdog functionality is required. It is suitable for applications needing both under-voltage and over-voltage detection. The low supply current makes it ideal for battery-operated systems. Consider the push-pull output capability if direct driving of logic gates is necessary without external pull-ups.

Supervisors Part Context

This part belongs to the TPS3124 series of voltage supervisors from Texas Instruments. It is categorized under PMIC - Power Management ICs. The device is distinct from other series like TPS3125 or TPS3128 due to its specific output configuration and lack of manual reset pin. It shares the SOT-23-5 form factor common to many TI supervisory circuits.
