  • Forum Post: TPS65920 Crystal Maximum ESR / Feedback Resistor Requirements

    Charles McCarthy Charles McCarthy
    Hello! I have two questions regarding the TPS65920 32.768kHz crystal specification: 1) The datasheet (SWCS037E) states that the maximum crystal ESR is 75 k-Ohms in Table 11-4. I am wondering if higher ESR crystals will work okay. Specifically, I have attached a URL for an Abracon AB06 32.768kHz Crystal...

    Eric Zuber Eric Zuber
    Hoping to validate my understanding of this circuit based on the TRM....in TPS65930, it looks like the 32KIN and related RTC circuitry are powered as long as there is a valid voltage on Vbat....so driving 32KIN with an external 1.8V oscillator is no problem as long as VBAT > 3.2V. I see no notes about...
