MAX9920規(guī)格書詳情
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
