C1+ +3.3V TO +6.6V VCC VOLTAGE C1- V+ DOUBLER 00071-016 Figure 16. ADM3222 Typical Operating Circuit The charge pump voltage converter consists of a 200 kHz oscillator and a switching matrix. The converter generates a 6.6 V supply from the input 3.3 V level. This is done in two stages by using a switched capacitor technique as illustrated in Figure 18 and Figure 19. First, the 3.3 V input supply is doubled to 6.6 V by using Capacitor C1 as the charge storage element. The +6.6 V level is then inverted to generate -6.6 V using C2 as the storage element. C3 is shown connected between V+ and VCC but is equally effective if connected between V+ and GND.

C1+ +3.3V TO +6.6V VCC VOLTAGE C1- V+ DOUBLER + CMOS technology is used to keep the power dissipation to an absolute minimum, allowing maximum battery life in portable applications. 0.1F + 10V + The ADM3202/ADM3222/ADM1385 are RS-232 line drivers/ receivers. Step-up voltage converters coupled with level-shifting transmitters and receivers allow RS-232 levels to be developed while operating from a single 3.3 V supply. ADM3202/ADM3222/ADM1385 Transmitter (Driver) Section HIGH BAUD RATE The drivers convert 3.3 V logic input levels into RS-232 output levels. With VCC = 3.3 V and driving an RS-232 load, the output voltage swing is typically 6 V. The ADM3202/ADM3222 feature high slew rates permitting data transmission at rates well in excess of the EIA/RS-232E specifications. RS-232 voltage levels are maintained at data rates up to 460 kbps even under worst-case loading conditions. This allows high speed data links between two terminals and is suitable for the new generation ISDN modem standards that require data rates of 230 kbps. The slew rate is internally controlled to less than 30 V/s to minimize EMI interference. Receiver Section The receivers are inverting level-shifters that accept RS-232 input levels and translate them into 3 V logic output levels. The inputs have internal 5 k, pull-down resistors to ground and are protected against overvoltages up to 30 V. Unconnected inputs are pulled to 0 V by the internal 5 k, pull-down resistor. This results in a Logic 1 output level for unconnected inputs or for inputs connected to GND. The receivers have Schmitt-trigger inputs with a hysteresis level of 0.4 V. This ensures error-free reception for both noisy inputs and for inputs with slow transition times. Rev.
