描述
The HIP2103 is a half-bridge driver designed for applications using DC motors, 3-phase brushless DC motors, or other similar loads. The two inputs (HI and LI) independently control the high-side driver (HO) and the low-side driver (LO). HI and LI can be configured to enable/disable the device, which lowers the number of connections to a microcontroller and the cost. The low IDD bias current in the Sleep mode prevents battery drain when the device is not in use, which eliminates the need for an external switch to disconnect the driver from the battery. Integrated pull-down resistors on all of the inputs (LI, HI, VDen, and VCen) reduce the need for external resistors. An active-low resistance pull-down on the LO output ensures that the low-side bridge FET remains off during the Sleep mode or when VDD is below the Undervoltage Lockout (UVLO) threshold.
