Description
The MAX20037/MAX20038 ICs combine a 3.5A automotive- grade step-down
converter, USB host charger adapter emulator, and USB protection switches for
automotive USB host applications. The device family also includes a USB load current-
sense amplifier and configurable feedback-adjustment circuit, designed to provide
automatic USB voltage compensation for voltage drops in captive cables often found in
automotive applications. The ICs limit the USB load current using both a fixed internal
peak-current threshold of the DC-DC converter and a user-configurable external USB
load current-sense amplifier threshold.
The ICs allow flexible configuration options for both stand-alone and supervised
applications, and can be programmed for desired operation using both external
programming resistors and/or internal I
2
C registers through the I
2
C bus.
The ICs are optimized for high-frequency operation and include programmable
frequency selection from 310kHz to 2.2MHz, allowing optimization of efficiency, noise,
and board space based on application requirements. The fully synchronous DC-DC
converters feature integrated high-side and low-side MOSFETs, an external SYNC
input/output, and can be configured for spread-spectrum operation.
The MAX20037/MAX20038 are are available in a small (5mm x 5mm) 28-pin TQFN
package designed to minimize required components and layout area.
