To enter the Shutdown Mode state, connect the equipment as follows:

• Power Supply PS #1: VIN of the BQ25186EVM at 0V or disconnected
• Power Supply PS #2: VBAT of the BQ25186EVM at 3.7V
• Scope Channel SC #1: VIN at TP5
• Scope Channel SC #2: VBAT at TP8
• Scope Channel SC #3: VSYS at TP6
• Scope Channel SC #4: TS/MR at TP11

Turn ON power supply #2. Enter Shutdown Mode by setting the EN_RST_SHIP bits in the SHIP_RST register (0x09) to 2b01. Users are in Shutdown Mode when the voltage on the SYS pin (SC #2) falls to 0V and the voltage on the TS/MR pin falls to 0V.

Alternatively, Ship Mode can be entered through a long button press. Turn ON power supply #2. With VSYS active (not in Ship Mode or Shutdown Mode), make sure that the PB_LPRESS_ACTION bits are set to 2b11: Enable Shutdown Mode. After holding the button SW1 for longer than MR_LPRESS (default: 2b01 (10s), the voltage on SYS (SC #3) falls to 0V.
