HIP2103, HIP2104
60V, 1A/2A Peak, Half-Bridge Driver with 4V UVLO
The HIP2103 and HIP2104 are half-bridge drivers
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.
The HIP2104 has a 12V linear regulator and a 3.3V
linear regulator with separate enable pins. The 12V
regulator provides internal bias for VDD and the 3.3V
regulator provides bias for an external microcontroller
(and/or other low voltage ICs), which eliminates the
need for discrete LDOs or DC/DC converters.
