General Description

The MAX9918/MAX9919/MAX9920 are single-supply, high-accuracy current-sense amplifiers with a high input common-mode range that extends from -20V to +75V. These amplifiers are well suited for current moni toring of inductive loads such as motors and solenoids, where common-mode voltages can become negative due to inductive kickback, reverse-battery conditions, or transient events.

Features

? -20V to +75V Input Common-Mode Voltage Range

? 400μV (max) Input Offset Voltage

? 0.6 (max) Gain Accuracy Error

? Uni- or Bidirectional Current Sensing

? Reference Input for Bidirectional OUT

? 120kHz, -3dB Bandwidth (MAX9919N)

? Single-Supply Operation (4.5V to 5.5V)

? 1mA Supply Current

? 0.5μA (typ) Shutdown Current

? Rail-to-Rail Output

? -40°C to +125°C Automotive Temperature Range

Applications

? H-Bridge Motor Current Sensing

? Solenoid Current Sensing

? Current Monitoring of Inductive Loads

? High- and Low-Side Precision Current Sensing

? 4x4 Transmission Control

? Electronic Throttle Control

? Super-Capacitor Charge/Discharge Monitoring in Hybrid Cars

? Precision High-Voltage Current Monitoring
