• CE is HIGH • The device is not in VCCLOWV mode • The device is not in SLEEP mode • The VCC voltage is lower than the ac overvoltage threshold (VCC < V ACOV ) • 30-ms delay is complete after initial power up • The REGN LDO and VREF LDO voltages are at the correct levels • Thermal shut (TSHUT) is not valid • TS fault is not detected
在上电的时候抓取VCC, /PG, VREF, REGN的波形，看是否有异常。查看 PH, LODRV, CE 波形看是否有异常
，好像电源指示不正常。好像STAT和\PG都是低电平。
