OBGZ11MP from OB On Bright Elec, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device ground reference. |
| 2 | FB | input | Feedback input pin. The PWM duty cycle is determined by the voltage level into this pin and the current-sense signal at Pin CS. Open loop OLP threshold ~4.4 V; input impedance ~30 kΩ. |
| 3 | PRT | input | Dual-function protection pin. Connect an NTC resistor to GND for external OTP detection; a resistor from Vaux adjusts the OVP trigger voltage. If both OTP and OVP are used, a diode should be connected between PRT and the NTC resistor. Absolute max input -0.3 to 7 V. |
| 4 | CS | input | Current sense input from the MOSFET source resistor. Internal current-limit threshold ~0.45 V (zero duty cycle); leading-edge blanking ~300 ns; OCP clamp ~0.72 V. |
| 5 | VCC | power_in | Power supply input. Recommended operating range 12 to 26 V. UVLO(ON) ~7.3 V, UVLO(OFF)/recovery ~16.2 V, OVP threshold ~28 V. Startup current ~2 µA, operating current ~2.5 mA. |
| 6 | Gate | output | Totem-pole gate driver output for the external power MOSFET. Includes soft-start on power-up to reduce MOSFET Vds stress. |
