DA9062 doesn't turn on rails when external crystal not presentPosted by xmarine007 30 points 7 replies
I have two sets of boards. On one set I have an external oscillator in the circuitry supporting the PMIC and the CRYSTAL bit is set (high) in register 0x098. Once programed with the OTP file and soldered to the board, the PMIC functions as expected - i.e. all rails are up at the correct values and are sequenced in the correct order.
On the second set of boards, the circuit surrounding the PMIC is nearly identical as above except I didn't design it with an external oscillator. the XTAL_IN and XTAL_OUT pins are connected to ground. However, I have accidentally used the same OPT file to program the PMICs on this set of boards as for the boards above, which means I have accidentally programmed the PMICs with the CRYSTAL bit turned on when I don't have an onboard oscillator.
When I power the board (from the 2nd set of board), the PMIC doesn't turn on. All voltage rails are at 0.0V.
I don't know why the PMICs don't turn on. The datasheet does not explicitly say what happens when you don't have an external oscillator but the PMIC is programed with the CRYSTAL bit set.
Does the DA9062 PMIC require that the CRYSTAL bit reflects the physical implementation (oscillator present)? What happens if that is not the case?
What else could be the issue -- why would the PMIC not turn on the rails in the second case, given the close similarities between the two sets of boards' circuitry?
