LTC4359IMS8#TRPBF
Analog Devices · Power Distribution Switches · MSOP-8
LTC4359IMS8#TRPBF from Analog Devices, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GATE | output | Gate drive output that enhances the external N-channel MOSFET when load current creates more than 30mV across it, and pulls GATE to SOURCE within 0.3µs during reverse current to turn the MOSFET off. |
| 2 | SOURCE | input | Source connection that is the return path of the gate fast pull-down and should be connected as close as possible to the source of the external N-channel MOSFET. |
| 3 | NC | unconnected | No connection; not internally connected. |
| 4 | IN | power_in | Voltage sense and supply voltage; IN is the anode of the ideal diode and its sensed voltage controls the MOSFET gate. |
| 5 | SHDN | input | Shutdown control input that shuts the part down to a low current mode when pulled below 0.6V, enables it when pulled above 2V or left open (internal 2.6µA pull-up), and can be pulled up to 100V or down to -40V with respect to VSS without damage. |
| 6 | VSS | power_in | Supply voltage return and device ground. |
| 7 | NC | unconnected | No connection; not internally connected. |
| 8 | OUT | power_out | Drain voltage sense and cathode of the ideal diode; connects directly or through a 2k resistor to the MOSFET drain and is the common output for ideal diode-OR configurations. |
