U6046B-MFPY

Overview

The U6046B-MFPY is a bipolar long-term timer designed for automotive applications to limit high-load operation time. It features an RC oscillator for timing, a debounced toggle input, and a relay driver output with integrated Z-diode protection. The device operates between 6V and 16V via VBatt, with provisions for 5V supply. Key functions include power-on reset, load-dump protection, and RF interference immunity compliant with ISO/TR7637-1. The delay time ranges from 3.7s to 20h, determined by external R2 and C2 components.

Feature Summary

RC Oscillator determines timing characteristics with delay range of 3.7s to 20h
Relay Driver Output with integrated 23-V Z-diode for inductive load protection
Debounced Inputs: ON, OFF, and TOGGLE switch functionality
Load-dump and RF Interference Protection compliant with ISO/TR7637-1

Applications

Rear Window Heating Timer
Long-term Timer for high loads in automotive environments
Automatic operation time limiting for current-consuming devices

Procurement Notes

Verify the ordering suffix MFPY corresponds to the SO8 (Small Outline) package configuration. Confirm Pb-free status as indicated in the ordering information table. Ensure compatibility with the specified bipolar technology and automotive qualification requirements before procurement.

Selection Notes

Select external resistor R2 and capacitor C2 values based on the desired oscillator frequency and resulting delay time using Table 6-1. For 12V systems, use R1=510Ω and C1=47µF. For 5V systems, connect Pin 7 to Pin 8 and omit R1/C1. Ensure the load current does not exceed 300mA static collector current.

Part Context

The U6046B-MFPY is part of the U6046B family of bi-polar long-term timers originally developed by Atmel Corporation. The 'MFPY' suffix specifically denotes the SO8 surface-mount package variant that is lead-free. This component serves as a specialized analog circuit for managing timed operations in harsh automotive electrical environments.
