The on-resistance of this driver at typical operating conditions is just 0.48Ω. This is highly advantageous from a thermal management perspective, as there is considerably less heat that needs to be dissipated – thereby leading to system cost and space savings.
The TC78H660FNG driver is suitable for a broad spectrum of potential applications – such as mobile devices running off a 3.7V Li-Ion battery and 5V USB-powered equipment, as well as 12V-rated household appliances. Supporting energy efficient operation, it has ultra-low current requirements when in standby mode, drawing 0.1µA. An array of safety features have been incorporated.
These include under-voltage lockout, over-current detection and thermal shut down. Keeping PCB utilisation to a minimum, this IC is supplied in a compact 5.0×6.4mm TSSOP16 package.
