Información del producto
Resumen del producto
MAX49925XATB+T is a bidirectional, wide positive and negative sensing range current-sense amplifier with fast PWM rejection. This CSA has an extended input protection range of -42V to +80V against reverse-battery and high-voltage spikes. The wider input protection range also helps relax TVS requirements, leading to lower BOM cost and reduced component size. It is well-suited for phase-current monitoring of inductive loads, such as motors and solenoids, where pulse-width modulation (PWM) is used to control the drive voltage and current. Typical applications include PWM H-bridge motor in-line/in-phase/winding current sensing, solenoid current sensing, current monitoring of inductive loads, battery stack monitors and high-power DC motors.
