PRODUCTION DATA
The EN/SYNC pin provides precision ON and OFF control for the TPSM63606E. Once the EN/SYNC pin voltage exceeds the rising threshold and VIN is above its minimum turn-on threshold, the device starts operation. The simplest way to enable the TPSM63606E is to connect EN/SYNC directly to VIN. This allows the TPSM63606E to start up when VIN is within its valid operating range. However, many applications benefit from the use of an enable divider network as shown in Figure 8-1, which establishes a precision input undervoltage lockout (UVLO). This can be used for sequencing, to prevent re-triggering the device when used with long input cables, or to reduce the occurrence of deep discharge of a battery power source. An external logic signal can also be used to drive the enable input to toggle the output on and off and for system sequencing or protection.
