OUT is asserted low when the 6 monitored input (VCC) drops below the internal VTH- threshold and remains low 1 until the monitored input exceeds the internal VTH+ threshold. OUT is asserted – OUT high when the monitored input (VCC) drops below the internal VTH- threshold and M remains high until the monitored input exceeds the internal VTH+ threshold.

These devices consume only 1µA of supply current with a 3.6V supply voltage. R1 MAX6461– MAX6466 Whenever VCC falls below the internal VTH- threshold, the output is asserted and remains asserted until VCC rises above VTH+ (VTH+ = VTH- ×1.05). All devices have R2 ±2.5% threshold accuracy over temperature and offer RESET OUTPUT protection to short voltage transients. These devices are OUT TIMEOUT STAGE ideal for low-cost and space-critical applications because they do not require external components for proper operation.

Choose the desired voltage threshold suffix from Table 1 and insert it in the blank spaces in the part number. There are 30 standard ver- sions with a required order increment of 2500 pieces. Sample stock generally is held on the standard versions only (Table 2). Nonstandard versions require a 10k-piece order increment. Contact factory for availability. All devices available in tape-and- reel only. Devices are available in both leaded and lead-free packaging. Specify lead-free by replacing “-T” with “+T” when ordering. Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product. No circuit patent licenses are implied. Maxim reserves the right to change the circuitry and specifications without notice at any time. 10 ____________________Maxim Integrated Products, 120 San Gabriel Drive, Sunnyvale, CA 94086 408-737-7600 © 2005 Maxim Integrated Products Printed USA is a registered trademark of Maxim Integrated Products, Inc.
