Description

Conditions

Transitory QPU_Off state, power on event occurs from LP_Off

state, after self-test is passed, QPU_Off is just a transitory state until

power up sequence starts.

1. LPM_OFF = 0

&& TBBEN = Low

&& TRIM_NOK = 0 && OTP_NOK = 0 && STEST_NOK=0

Power up event from QPU_Off state

2. LPM_OFF = 1

&& (PWRON = 1 && OTP_PWRON_MODE = 0)

&& UVDET < VIN < VIN_OVLO (or VIN_OVLO disabled

&& Tj < TSD

&& TRIM_NOK = 0 && OTP_NOK = 0 && STEST_NOK=0

Power up event from QPU_Off state

3. LPM_OFF = 1

&& (PWRON H to L && OTP_PWRON_MODE = 1)

&& UVDET < VIN < VIN_OVLO (or VIN_OVLO disabled)

&& Tj < TSD

&& TRIM_NOK = 0 && OTP_NOK = 0 && STEST_NOK=0

Power up event from QPU_Off state

4. TBBEN = High

&& (PWRON = 1 && OTP_PWRON_MODE = 0)

&& UVDET < VIN < VIN_OVLO (or VIN_OVLO disabled

&& Tj < TSD

&& TRIM_NOK = 0 && OTP_NOK = 0 && STEST_NOK=0

Transition L

QPU_Off to power up

Power up event from QPU_Off state

5. TBBEN = High

&& (PWRON H to L && OTP_PWRON_MODE = 1)

&& UVDET < VIN < VIN_OVLO (or VIN_OVLO disabled)

&& Tj < TSD

&& TRIM_NOK = 0 && OTP_NOK = 0 && STEST_NOK=0

Transition M

Power up sequence to system ON

1. RESETBMCU is released as part of the power up sequence

Requested turn off event

1. OTP_PWRON_MODE = 0 && PWRON = 0

Requested turn off event

2. OTP_PWRON_MODE = 1 && (PWRON H to L && PWRON = low

for t > TRESET)

Requested turn off event

3. PMIC_OFF = 1 && 500µs_Shutdown_Timer_Expired

Transition N

System ON to power down (turn off)

Protective turn off event (no PMIC fault)

4. VIN_OVLO_SDWN=1 && VIN_OVLO detected for longer than

VIN_OVLO_DBNC time

Turn off event due to PMIC fault

1. Fault Timer expired

Turn off event due to PMIC fault

2. FAULT_CNT = FAULT_MAX_CNT

Transition Z

System ON to power down (fault)

Turn off event due to PMIC fault

3. Thermal shutdown Tj > TSD

Transition O

Power down (turn off) to LP_Off

Requested turn off event moves directly to LP_Off

1. Power down sequences finished

Transition Q

Power up to power down (fault)

Power up failure

1. Failure during power up sequence
