LMP8645HVMKX

Texas Instruments · Current-Sensing Amplifiers · TSOT-23-6

LMP8645HVMKX from Texas Instruments, in a TSOT-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 VOUT output Single-ended buffered analog output. Output voltage equals I_sense × R_sense × (R_G × transconductance) referenced to V-. Output impedance is low; swings between V- and V+ rails.
2 V- power_in Negative supply voltage / reference. Typically tied to system ground for single-supply operation; VOUT is referenced to this pin. Total supply (V+ - V-) must be 2.7 V to 12 V.
3 +IN input Positive (non-inverting) differential input; connect to the high-side of the external sense resistor. Common-mode range is -2 V to +76 V (LMP8645HV), independent of the supply rail. Input bias current typ 12 µA.
4 -IN input Negative (inverting) differential input; connect to the low-side of the external sense resistor. Same -2 V to +76 V common-mode range as +IN. Max differential input +IN-(-IN) is 6 V.
5 RG passive External gain-setting resistor pin. Gain = R_G × 200 µA/V (transconductance). Resistor is tied between RG and V-; overall gain accuracy is 2% max plus R_G tolerance. Absolute voltage on this pin limited to 13.2 V.
6 V+ power_in Positive supply voltage. 2.7 V to 12 V relative to V-. Bypass locally with a ceramic capacitor to V-.
