Reset structure

The RESET# signal of the TQMLS1012AL is available via signals RESET_1V8# and RESET_3V3# on the MBLS1012AL. Signal

RESET_3V3# on the MBLS1012AL is generated from RESET_1V8#.

Attention: Signal RESET_3V3#

Signal RESET_3V3# is designed as reset triggering signal. The RESET_1V8# signal must be used to

send a reset signal to the system.

The global reset is also used by the voltage monitoring. The Supervisor TPS3808G01DBV is used for this purpose. It monitors the

5 V input voltage and includes the manual reset button. The undervoltage threshold is set to 4.455 V, the delay until the reset

signal is enabled again is set to 300 ms. On the MBLS1012AL a red LED indicates a reset, see Table 34.
In addition to the signals described above, the MBLS1012AL offers further options for a complete or partial reset of the

TQMLS1012AL. All important interfaces are connected to the reset signal via AND gates in such a way that, in addition to the

global reset, they can be reset individually via a GPIO signal of the IO expander. In addition, the power supplies of the WLAN and

PCIe cards can be switched separately. The following table shows the used signals.

Remark

RESET_1V8#

TQMLS1012AL

High

Activated by the TQMLS1012AL during power sequencing.
Is activated by means of a delay buffer approx. 140 to 460 ms

after switching on the TQMLS1012AL supply.

RESET_3V3#
