MICROPOWER FIXED GAIN OF 50 CURRENT MONITOR
Absolute maximum ratings
Voltage on S+1 ................................................. -0.5V to 20V
Voltage on S-1,2, OUT1 ............................ -0.5V to VS++0.5V
VSENSE3........................................................... -0.5V to +2.5V
Junction temperature ........................................ -40 to125ºC
Storage temperature ........................................ -55 to 150ºC
Package power dissipation (TA = 25ºC)
TDFN1812-4 ................................................................. mW
These are stress ratings only. Operation outside the absolute
maximum ratings may cause device failure. Operation at the
absolute maximum rating for extended periods may reduce
device reliability
Notes: 1.
Measured with respect to GND pin
2. Subject to absolute maximum VSENSE not being
exceeded.
3. VSENSE is defined as the voltage difference across
the sense resistor, RS.
4. The usable VSENSE range is limited by the output
voltage range; and as such will be reduced at lower
VS+ values.
Semiconductor devices are ESD sensitive and may be
damaged by exposure to ESD events. Suitable ESD
precautions should be taken when handling and
transporting these devices.
