µCool Portfolio of Power MOSFETs for Portable Applications
It’s a device by ON Semoconductor in reply for smaller, thinner, faster, cooler running and more reliable MOSFET devices.
The µCool™ products feature exceptional thermal resistance (38° C/W) and power ratings (1.9 W) in an impressively small 42 mm footprint.
The devices:
- The 20 V P-Channel Single NTLJS3113PT1G and the dual NTLJD3115PT1G are both optimized for lithium-ion battery charging applications with RDS(on) at 4.5 V of 42 mohms and 100 mohms respectively.
- The 20 V P-Channel FETKy© NTLJF3117PT1G (100mohms) is optimized to convert the 3 V to 4 V battery voltage into 1.1 V to power the microprocessor.
- The 30 V N-Channel Single NTLJS4159NT1G (35 mohms) and FETKy NTLJF4156NT1G (70 mohms) are both optimized for synchronous boost applications such as white LED backlight voltage.
- The 30 V N-Channel dual NTLJD4116NT1G (70 mohms) is optimized for low side switching such as camera strobe and flash.
ON Semiconductor’s latest MOSFETs offer yet another feaaaaature: an exposed flag on the bottom surface that acts as a drain contact and heat dissipation path. It allows for either greater power handling or operation at a lower junction temperature. This is important in battery operated devices as it extends the life time of the battery by lowering junction temperature equates to lower RDS(on) or less power loss.
