Texas Instruments BQ3285LFSS-A1TR
- Part Number:
- BQ3285LFSS-A1TR
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3004617-BQ3285LFSS-A1TR
- Description:
- IC RTC CLK/CALENDAR PAR 24-QSOP
- ECAD Model:
-
- Datasheet:
- BQ3285E,L
Description
The time-base oscillator is critical to the time-keeping functions of the bq3285, bq4285, and bq4845 series of Real-Time-Clocks (RTCs). The RTC time-base oscillator is designed to work with an external piezoelectric 32.768kHz crystal. The crystal can be represented by its electrical equivalent circuit and associated parameters. The basic circuit can be resolved into equivalent resistive (R) and reactive (X) components.
Features
Designed to work with an external piezoelectric 32.768kHz crystal
Equivalent crystal impedance varies with the frequency of oscillation
Crystal appears purely resistive at two points
Applications
Time-keeping functions of the bq3285, bq4285, and bq4845 series of RTCs
