FT7521L6X

Supervisors Overview

The FT7521L6X is a reset timer integrated circuit manufactured by onsemi, designed to provide a fixed delay and reset pulse for system supervision. It operates within a supply voltage range of 1.8 V to 5 V and functions across an industrial temperature range of -40°C to +85°C. The device features an open-drain output type and is housed in a MicroPAK-6 surface-mount package. It belongs to the FTL7522 series and supports SMD/SMT installation styles with power dissipation rated at 5 mW.

Supervisors Feature Summary

• Provides a fixed delay timer function with a dedicated reset pulse output
• Features an open-drain output configuration for flexible interfacing
• Operates with low supply voltage requirements suitable for portable applications

Supervisors Applications

• Mobile device reset supervision
• System reset timing control
• Low current consumption timer circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance details via official datasheets before integration. Ensure storage conditions meet semiconductor handling standards to prevent degradation. Cross-reference pinouts with updated documentation as legacy components may have revision differences.

Supervisors Selection Notes

Select this component when a fixed delay reset pulse is required for systems operating between 1.8 V and 5 V. Consider the MicroPAK-6 package size for space-constrained designs. Evaluate thermal performance against the 5 mW dissipation rating. Compare against similar reset timers if configurable delays are needed instead of fixed timing.

Supervisors Part Context

The FT7521L6X is part of onsemi's standard product lineup focused on timing and support products. It falls under the broader category of clock and timer ICs, specifically serving as a reset supervisor. The device complements other reset timers like the FT7511 and FTL7522 series, offering a specialized solution for fixed-delay applications in consumer and industrial electronics.
