IC MTR DRVR 4.5-5.5V 15MULTIWATT

Parameter	Symbol	Min	Typ	Max	Unit	Description
Supply Voltage	Vcc	4.5	-	5.5	V	Operating voltage range
Output Current	Iout	-	100	150	mA	Continuous output current
Power Dissipation	Pd	-	-	625	mW	Maximum power dissipation at TA = 25°C
Operating Temperature	Topr	-40	-	85	°C	Ambient operating temperature range
Storage Temperature	Tstg	-65	-	150	°C	Temperature range for storage
Junction Temperature	Tj	-40	-	125	°C	Maximum junction temperature

Instructions:

1. Power Supply Requirements: Ensure the supply voltage (Vcc) is within the specified range of 4.5V to 5.5V.
2. Output Current Management: Do not exceed the maximum continuous output current of 150mA to avoid damaging the device.
3. Thermal Considerations: Keep the junction temperature below 125°C. Use appropriate heat sinking if necessary, especially under high load conditions.
4. Environmental Conditions: Operate the device within the ambient temperature range of -40°C to 85°C and store it between -65°C and 150°C.
5. Power Dissipation Limit: Monitor the power dissipation to ensure it does not exceed 625mW at room temperature (25°C) to prevent overheating.

Note: Always refer to the manufacturer's datasheet for detailed specifications and application notes.
