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.
