Product Description

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
