Active-Low Interrupt Source. Program the INT output as push-pull or open-
drain with the irq_mode bit (bit 1 of special-function register 2, see Tables 15
and 16).
Active-Low Reset Input. Drive RESET low to asynchronously reset the
MAX3301E/MAX3302E.
I
ID Input. ID_IN is internally pulled up to V
ID bits 3 and 5 of the interrupt source register (see Table 10).
USB Differential Data Input/Output. Connect D- to the D- terminal of the USB
connector through a 27.4Ω ±1% series resistor.
USB Differential Data Input/Output. Connect D+ to the D+ terminal of the USB
connector through a 27.4Ω ±1% series resistor.
Single-Ended Receiver Output. VM functions as a receiver output in all
operating modes. VM duplicates D-.
USB Transceiver Regulated Output Voltage. TRM provides a regulated 3.3V
output. Bypass TRM to GND with a 1µF ceramic capacitor installed as close
to the device as possible. TRM normally derives power from V
provides power to internal circuitry and provides the pullup voltage for the
internal USB pullup resistor. Do not use TRM to power external circuitry. The
reg_sel bit (bit 3 of special-function register 2, see Table 15 and Table 16)
controls the TRM power source with software.
Single-Ended Receiver Output. VP functions as a receiver output in all
operating modes. VP duplicates D+.
USB Bus Power. Use V
to power the internal linear regulator. Bits 5 to 7 of control register 2 (see
Table 8) control the charging and discharging functions of V
Charge-Pump Flying-Capacitor Positive Terminal
Exposed Paddle. Connect EP to GND or leave unconnected.
