使用BQ7595204原理图跟评估板是一样的，但是板子一上电就激活了，REG1有3.3V,TS2接近0V，这是什么情况，
您好，推出shutdown mode条件请参考下面内容：
Exiting SHUTDOWN MODE:
While in SHUTDOWN mode, TS2 will idle high with a weak pull-up of ~4.6Mohm. To WAKE the device, the TS2 pin must be pulled to GND, or the LD pin must be pulled above ~1.45V. Once this occurs, TS2 will stay around 0V weakly. Upon waking from SHUTDOWN, the device will load OTP settings into the BQ769x2 device registers. Any register settings that were not programmed into OTP will be reset to default upon WAKEUP.
One exception to the typical WAKE procedure is SHUTDOWN caused by low VBAT voltage. If voltage is brought up from below VPORA – VPORA_HYS, then the device will WAKE up. Please note that the Power:Shutdown:Shutdown Stack Voltage must be above VPORA – VPORA_HYS , or the device will enter SHUTDOWN mode triggered by low stack voltage and can only be awakened by pulling the TS2 pin LOW or the LD pin HIGH.
When the device is wakened from SHUTDOWN, it generally requires approximately 200-300ms for the internal circuitry to power up, load settings from OTP memory, perform initial measurements, evaluate those relative to enabled protections, then to enable FETs if conditions allow. This can be much longer depending on settings. Please see Table 16-2 from the Datasheet for more precise timing specifications:
To combat inadvertent WAKEUP during SHUTDOWN mode, the BQ769x2 can also be configured to automatically re-enter SHUTDOWN mode after a period of time configured in Power:Shutdown:Auto Shutdown Time. The BQ769x2 will only auto-SHUTDOWN if the device WAKES from SHUTDOWN mode without any valid communications occurring or any charge or discharge current detected. These precautions prevent the device from entering SHUTDOWN mode in the case of intentional WAKEUP.
For a summary of common methods used to transition between power modes, please see Figure7-1 from the Technical Reference Manual.
