Toshiba Electronic Devices & Storage Corporation has launched an H-bridge motor driver, the TC78H660FNG, which is housed in a TSSOP16 package with a widely used pin-assignment. This is Toshiba’s latest addition to its line-up of drivers for brushed DC motors and stepping motors for applications that include mobile devices and home appliances.
The company’s new-generation DMOS process allows TC78H660FNG to achieve a low ON resistance of 0.48Ω at its maximum rating of 18V/2.0A and reduces heat generation compared with Toshiba’s current products.
The new driver also has a regulator for driving internal circuits, and can drive a motor with a single power supply ranging from 2.5V to 16V. Its wide range of applications include mobile devices powered by a 3.7V lithium-ion battery, 5V USB powered devices, and 12V system devices for home appliances. It 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
The battery-powered mobile devices include robots, smart meters, home appliances, and toys, etc.
