board logic. The regulator at VR2 energizes the +5V rail and provides power the OTG USB
bus when the board is configured for host mode applications.
The M52210DEMO is designed to allow application development while powered from the USB
BDM. A 2.0mm barrel connector and a 2-position, screw-type, terminal block (BATT) has been
applied to support stand-alone operation. The board may also be powered through connector
J1. Additionally, the board may be configured to supply power through connector J1 to exter-
nal circuitry.
An ON/OFF switch allows the user to quickly and easily connect and disconnect the +3.3V
logic voltage rail. The +5V voltage rail supplies power to the USB bus through the MAB con-
nector at J2 only and is not affected by the position of the ON/OFF switch.
When using the integrated USB BDM, the board draws power from the USB bus. Excessive
current drain will violate the USB specification causing the USB bus to disconnect forcing a
POR. Total current consumption of the board and any connected circuitry, therefore, must be
less than 500mA.
USB current is limited to 500mA maximum. Excessive current drain will cause the USB bus to
disconnect causing the DEMO board to reset. This may also cause damage to the DEMO
board and the host PC.
The installed barrel connector accepts a center-positive, 2.1mm barrel plug. The terminal
block accepts wire sizes ranging from 28ga to 16ga. Voltage input must be in the range be-
tween +6V and +15V. At no time should input voltage exceed +15V as damage to the board
may result. The terminal block input is connected directly to the upper voltage rail. Input pro-
tection is not applied on this voltage input. The user must exercise caution when using the
terminal block to input power to the board.
Voltage supplied through connector J1 is also connected directly to the board voltage rails. No
protection is applied on this input and the user must exercise caution when powering the board
from connector J1.
Input protection is NOT applied to the J1 or BATT power inputs. Excessive input voltage or
current will damage the board.
Power Jack
The PWR power jack consists of a 2.1mm, center-positive, barrel connector. Voltage applied
at this connector should range between +6V and +12V. Input voltage should be limited to
+12VDC to prevent excessive heating of the voltage regulators.
