MAX49925EVKIT#

MAX49925 evaluation kit (EV kit) is a fully tested and assembled circuit that demonstrates the capabilities of the MAX49925, high-precision, high-voltage, bidirectional current sense amplifier for PWM applications, such as servo motor control and solenoid drive. The MAX49925 are ideal for 48V, or less BLDC, induction motor applications (such as robotics), pick-and-place machines, 3D prints, or other servo motor control systems. The MAX49925 has an extended protective immunity from -42V to +80V, providing protection against reverse battery and high voltage spikes. This also can reduce the BOM complexity at the system level since a smaller TVS might be required. The MAX49925 EV kit is available in a 2” x 2” PCB and operates over the automotive temperature range of -40°C to +125°C. This EV kit demonstrates the MAX49925 in a 10-pin TDFN package, with four gain options 10V/V, 20V/V, 50V/V, 100V/V by the combination of the gain1 and gain2 pins.
