The LM1815M from Texas Instruments is an adaptive sense amplifier designed for motor control applications. This IC provides a one-shot pulse output synchronized with the negative-going zero crossing of a ground-referenced input signal, such as from a variable reluctance magnetic pick-up coil.
Key features include adaptive hysteresis that varies with input signal amplitude, enabling reliable sensing even in noisy environments. It operates from a single supply voltage ranging from 2V to 12V and can handle a wide input signal range from 100 mV P-P up to over 120V P-P with an external resistor. The device also features CMOS compatible logic outputs.
Packaged in a 14-SOIC surface mount package, the LM1815M is rated for an operating temperature range of -40°C to 125°C. This part is obsolete and no longer in production, with LM1815MX/NOPB listed as a potential replacement with upgraded functionality.
Applications for this sensor interface IC include motor control systems requiring precise timing references based on variable reluctance sensor inputs.
