TPS3808: 监控DSP TMS320F28377 供电及reset

Part Number: TPS3808
Other Parts Discussed in Thread: TPS3801

采用TPS3808系列芯片来监控TMS320F28377芯片的工作电压:

3.3V_LDO 采用 ADP3339AKCZ-3.3, 输出电压范围为Vcc_min= 3.2373V (-1.9% of 3.3V)

1.2V_LDO 由3.3V转换,IC为AMS1117-1.2, Vin_min=1.152V (-4% of 1.2V)

 

请问依据上述LDO的选型,选择 TPS3808G09作为1.2V监控芯片,TPS3808G33作为3.3V 的电压监控芯片,选型是否合适?电路设计是否有问题?

并将上电复位Reset时间设为130mS(由C606=22nf决定)是否能够满足DSP TMS320F28377的应用需求?
