RE46C119S16TF

Sensor And Detector Interfaces Overview

The RE46C119S16TF is a CMOS integrated circuit designed for low voltage regulation and piezoelectric horn driving. It integrates a switched capacitor charge pump boost regulator that converts the VDD supply to a regulated 12V output (VPOS), a 3V low-dropout voltage regulator, and a bi-directional interconnect logic block. The device features a maximum quiescent supply current of 6.5uA when inactive, a low battery detection interface with an analog output proportional to VDD, and a power good status pin. It operates within a supply voltage range of 6V to 12V and supports an operating temperature range from -40°C to +85°C.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'S16TF' against the manufacturer's official documentation to confirm package type and RoHS compliance status. Ensure ordering quantities align with standard reel packaging requirements specified in the product datasheet. Confirm lead times directly with authorized distributors as manufacturing schedules may vary.

Sensor And Detector Interfaces Selection Notes

Select this component when a single IC solution is required for both audio signaling via a piezoelectric horn and microprocessor voltage regulation. The built-in interconnect logic simplifies multi-unit alarm systems. Verify that the external capacitors meet the ESR and capacitance recommendations to ensure stable operation of the charge pump and LDO circuits.

Sensor And Detector Interfaces Part Context

This part belongs to the RE46C series of specialized ASICs developed by R&E International, now a subsidiary of Microchip Technology. These devices are optimized for battery-powered safety and security applications requiring minimal standby current and integrated high-voltage generation capabilities without external discrete components.

Sensor And Detector Interfaces Replacement Considerations

Consult the official datasheet for alternative part numbers within the RE46C family that offer different timer modes or package options. No direct cross-manufacturer substitutes are documented; verify pin compatibility and electrical specifications before considering any third-party alternatives.
