STGAP2HS Standby function 6.7 Standby function
In order to reduce the power consumption of both control interface and gate driving sides the device can be put in standby mode. In standby mode the quiescent current from VDD and VH supply pins is reduced to IQDDSBY and IQHSBY respectively, and the output remains in “safe state” (the output is actively forced low). The way to enter standby is to keep both IN+ and IN- high (“standby” value) for a time longer than tSTBY. During stand-by the inputs can change from the “standby” value. To exit stand-by, IN+ and IN- must be put in any combination different from the “standby” value for a time longer than tstbyfilt, and then in the “standby” value for a time t such that tWUP<t <tSTBY. When the input configuration is changed from the “standby” value the output is enabled and set according to inputs state after a time tawake.
