Toshiba has launched an H-bridge motor driver to its line-up of drivers for brushed DC motors and stepping motors for applications that include mobile devices and home appliances: the TC78H660FNG. It’s housed in a TSSOP16 package with a widely used pin-assignment.
Toshiba’s new-generation DMOS process allows the TC78H660FNG to achieve a low ON resistance of 0.48Ω, at its maximum rating of 18V/2.0A. It also reduces heat generation compared with Toshiba’s current products.
The new driver has a regulator for driving internal circuits and can drive a motor with a single power supply, ranging from 2.5 to 16V. Its wide range of applications includes mobile devices powered by a 3.7V lithium-ion battery, 5V USB powered devices and 12V system devices for home appliances. It also supports a low 1.8V interface.
Features
- Single power drive, simple PWM control
- Low ON resistance reduces heat generation compared with Toshiba’s current products. (Ron=0.48Ω (upper + lower: typ.) @VM=12V, Ta = 25°C)
- Low current consumption (ultra-low standby current: 0.1μA or less @Ta=25°C)
Applications
Battery-powered mobile devices, including robots and toys; home appliances including refrigerators, smart meters, etc.
