MAX3450E/MAX3451E/MAX3452E
ages (VL) from +1.65V to +3.6V. Integrated ±15kV ESD
protection protects the D+ and D- USB I/O ports.
The MAX3451E features an enumerate function provid-
ing an internal 1.5kΩ pullup resistor to VTRM. The enu-
merate function disconnects the 1.5kΩ pullup resistor,
allowing the MAX3451E to simulate a bus disconnect
while powered and connected to the USB cable. The
MAX3450E is pin-for-pin compatible with Micrel’s
MIC2550A. The MAX3452E features a BD output that
asserts high if VBUS is greater than +4.0V. BD asserts
low if VBUS is less than +3.6V. The MAX3450E and
MAX3452E require external pullup resistors from either
D+ or D- to VTRM to set the bus speed.
Applications Information
Power-Supply Configurations
Normal Operating Mode
Connect VL and VBUS to system power supplies
(Table 1). Connect VL to a +1.65V to +3.6V supply.
Connect VBUS to a +4.0V to +5.5V supply. Alternatively,
the MAX3450E and MAX3451E can derive power from
a single Li+ battery. Connect the battery to VBUS. VTRM
remains above +3.0V for VBUS as low as +3.1V.
Additionally, the MAX3450E and MAX3451E can derive
power from a +3.3V ±10% voltage regulator. Connect
VBUS and VTRM to an external +3.3V voltage regulator.
VBUS no longer consumes current to power the internal
linear regulator in this configuration.
Disable Mode
Connect VBUS to a system power supply and leave VL
unconnected or connect to GND. D+ and D- enter a tri-
state mode and VBUS (or VBUS and VTRM) consumes
less than 20A of supply current. D+ and D- withstand
external signals up to +5.5V in disable mode (Table 2).
Sharing Mode
Connect VL to a system power supply and leave VBUS
(or VBUS and VTRM) unconnected or connect to GND.
D+ and D- enter a tri-state mode, allowing other circuitry
to share the USB D+ and D- lines, and VL consumes less
than 20A of supply current. D+ and D- withstand
external signals up to +5.5V in sharing mode (Table 2).
