Wuxi Maxinmicro · Surge Protection Devices (SPDs) · MSOP-10
LMX5069MS from Wuxi Maxinmicro, in a MSOP-10. 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 | SENSE | input | Current sense input: the voltage across the current-sense resistor RSENSE is measured from VIN to this pin, and when it reaches the current-limit threshold (value not legible in extracted text) the load current is limited and the fault timer activates. |
| 2 | VIN | power_in | Positive supply input; a small ceramic bypass capacitor placed close to this pin is recommended to suppress transients that occur when the load current is switched off. |
| 3 | UVLO | input | Dual-function control pin: when used as an ENABLE pin and pulled down it shuts off the internal pass MOSFET, and as a UVLO pin it programs the undervoltage trip point through an external resistor divider. |
| 4 | OVLO | input | Overvoltage lockout input: an external resistor divider from the system input voltage sets the overvoltage turn-off threshold, and an internal current source provides hysteresis (disable threshold value not legible in extracted text). |
| 5 | GND | power_in | Circuit ground. |
| 6 | Timer | passive | Timing capacitor pin: an external capacitor connected here sets the insertion time delay, the fault timeout period and the restart timing. |
| 7 | PWR | passive | Power limit set: an external resistor connected to this pin, in conjunction with the current-sense resistor, sets the maximum power dissipation allowed in the external series pass MOSFET. |
| 8 | PGD | output | Open-drain power good indicator output: it is active when the external MOSFET VDS decreases below the threshold and switches low when VDS rises above it (threshold values not legible in extracted text). |
| 9 | OUT | input | Output feedback input: connect to the output rail at the external MOSFET source, used internally to determine MOSFET VDS for power limiting and to control the PGD indicator. |
| 10 | GATE | output | Gate drive output: connect to the external MOSFET gate; when enabled, the gate voltage is typically above the OUT pin by a value not legible in extracted text. |
