| PIN | I/O(1) | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
|
IN |
1 | P | Power input for internal FET. |
| Vcc | 2 | P | Supply input for internal circuits of the device. |
|
OVP |
3 | I | Overvoltage protection input. This pin can be connected to GND for disabling OVP. |
| FLT | 4 | O | Active low fault output. See the FLT Pin Indication for Different Events section for different FLT pin indications. |
|
EN/SHDN |
5 | I | Enable or shutdown input. |
| PDLY | 6 | I/O | TPS16410, TPS16411: Input for blanking time for power limiting. Connect a capacitor to set PDLY blanking time. |
| IDLY | TPS16412, TPS16413: Input for blanking time for current limiting. Connect a capacitor to set IDLY blanking time. | ||
|
dVdT |
7 | I/O | Output slew control input. Connect a capacitor to set the output slew rate. If not used, this pin can be left open. |
| PLIM | 8 | I/O | TPS16410, TPS16411: Power limit input. Connect a resistor to set PLIM setpoint. |
| ILIM | TPS16412, TPS16413: Current limit input. Connect a resistor to set ILIM setpoint. | ||
| IOCP/IMON | 9 | I/O | Overcurrent protection input and current monitoring output for output current. Output current can be sensed by reading voltage on this pin. Connect a resistor to set IOCP set-point and for reading output current. |
| OUT | 10 | P | Power output from internal FET. |
| PowerPAD/GND | — | G | GND connection for the device. PowerPAD? must be connected to GND of input power supply. Connect PowerPAD to GND plane on PCB using multiple vias for enhanced thermal performance. |
