Other Parts Discussed in Thread: TPS65910 , AM3352 现象:使用TPS65910配合AM3352,在后备电池模式下,使用3V电池给65910的Vbackup供电,输出VTRC电源1.8V给ARM供电,ARM此时仅RTC工作。在这种方式下,测试3V电池输出电流为35uA,1.8VRTC处电流为22uA,无论如何修改配置,电流基本没有变化。这种电流消耗都远大于TPS65910的最大10uA电流,且65910的EVM板上还可以使用EECEN0F204AK的超级电容当做电池使用…
Other Parts Discussed in Thread: TPS65910 大家好:
我用的是Ti 官方的EVM开发板,Base板的版本是1.5c的,电源管理芯片是tps65910A3,我现在想通过Poweroff命令实现关机,在/driver/mfd/tps65910.c的文件中有tps65910_power_off(void)函数,其中tps65910_reg_set_bits(tps65910, TPS65910_DEVCTRL, DEVCTRL_PWR_OFF_MASK)是通过置PWR_OFF位来设置电源管理芯片…
Other Parts Discussed in Thread: TPS65910 , AM3359 TPS65910具有两个I2C接口,数据手册是这样说的:TPS65910 has two slave I2C interfaces: one is a general-purpose interface to control the internal configuration registers, the second is dedicated to SmartReflex applications…
Other Parts Discussed in Thread: AM3352 , TPS65910 According to TPS65910Ax User's Guide For AM335x,the VDDSHVx delays 2000uS after VDDS_DDR.In our design,the power supply of VDDSHVx is 3.3 V , and in PCB the power 3.3 V is source from DC/DC module ou…
