Full Half-Bridge Drivers
Devices in the bridge driver PMIC (Power Management Integrated Circuit) family incorporate two or more power transistors along with circuitry required to operate them as switches under the control of an external device. The transistors are typically configured internally in series-connected pairs known as half-bridges, such that the junction between any given pair can be connected to either of two power supply rails. They are commonly used to translate low-level signals provided by a control device such as a microcontroller into the higher power signals required to operate an actuator such as a stepper or brushless motor.
