The TPS2663x devices respond differently to overload with MODE pin configurations. The operational differences are explained in Table 9-1.
MODE Pin Configuration | Overload Protection Operation | Device |
---|---|---|
Open | Active Current limiting at 1x for a maximum duration of tCL_PLIM(dly). There after Latches OFF. Latch reset by toggling SHDN low to high or UVLO low to high or power cycling IN_SYS. | TPS26630, TPS26632 |
Active Current limiting at 2x for tCB(dly) duration followed with 1x current limiting for a maximum duration of tCL_PLIM(dly). There after Latches OFF. Latch reset by toggling SHDN low to high or UVLO low to high or power cycling IN_SYS. | TPS26631, TPS26633, TPS26635, TPS26636 | |
Shorted to GND | Active Current limiting at 1x for a maximum duration of tCL_PLIM(dly). There after auto-retries after a delay of t(TSD_retry). | TPS26630, TPS26632 |
Active Current limiting at 2x for tCB(dly) duration followed with 1x current limiting for a maximum duration of tCL_PLIM(dly). There after auto-retries after a delay of t(TSD_retry). | TPS26631, TPS26633, TPS26635 |
Refer to Figure 8-2 for more information on tCB(dly) and tCL_PLIM(dly) parameter measurement information.
