Operation Modes

TLE75620-EST has the following operation modes:

•Sleep mode

• Idle mode

•Active mode

• Limp Home mode

The transition between operation modes is determined according to following levels and states:

• logic level at IDLE pin

• logic level at INn pins

• OUT.OUTn bits state

• HWCR.ACT bit state

• HWCR_PWM.PWM0 and HWCR_PWM.PWM1 bits state

The state diagram including the possible transitions is shown in Figure 13. The behaviour of TLE75620-EST as

well as some parameters may change in dependence from the operation mode of the device. Furthermore,

due to the undervoltage detection circuitry which monitors VS and VDD supply voltages, some changes within

the same operation mode can be seen accordingly.

The operation mode of the TLE75620-EST can be observed by:

• status of output channels

• status of SPI registers

• current consumption at VDD pin (IVDD)

• current consumption at VS pin (IVS)

The default operation mode to switch ON the loads is Active mode. If the device is not in Active mode and a

request to switch ON one or more outputs comes (via SPI or via Input pins), it will switch into Active or Limp

Home mode, according to IDLE pin status. Due to the time needed for such transitions, output turn-on time

tON will be extended due to the mode transition latency.
