MAX889TESA+T
Analog Devices Inc Maxim Integrated · Charge Pumps · SOIC-8
MAX889TESA+T from Analog Devices Inc Maxim Integrated, in a SOIC-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 | IN | power_in | Power-supply positive voltage input, specified for +2.7V to +5.5V with an undervoltage lockout threshold of 2.3V to 2.6V (absolute maximum +6V to GND). |
| 2 | CAP+ | passive | Positive terminal of the flying capacitor; its absolute maximum rating to GND is -0.3V to (VIN + 0.3V). |
| 3 | GND | power_in | Power ground, the reference for the IN, FB, SHDN and CAP+ ratings and the power-stage return. |
| 4 | CAP- | passive | Negative terminal of the flying capacitor; its rating to GND is (VOUT - 0.3V) to +0.3V. |
| 5 | OUT | power_out | Inverting charge-pump output, regulated from -2.5V to -VIN for loads up to 200mA (OUT to GND rated -6V to +0.3V). |
| 6 | SHDN | input | Shutdown control input (CMOS-compatible): drive low to shut down the device, connect to IN for normal operation; logic high is 0.7 x VIN minimum and logic low is 0.3 x VIN maximum. |
| 7 | FB | input | Feedback input: connect to a resistor divider from IN (or another positive reference) to OUT for regulated output, or to IN for free-run mode; the feedback loop servos FB to GND. |
| 8 | AGND | power_in | Analog ground, specified together with GND so that AGND to GND is limited to -0.3V to +0.3V. |
