It can source an output current in excess of 5.0 mA. 5 VO Charge Pump Capacitor + This is the positive pin for the capacitor in the inverting charge pump. 6 Gnd This pin is Ground for both signal and power circuitry. 7 VO Charge Pump Capacitor – This is the negative pin for the capacitor in the inverting charge pump. 8 Gate Drive Output This is the output of the gate amplifier which directly drives the gate of an N–Channel MOSFET. It can sink and source peak currents up to 3.0 mA. 9 Tx Power Control Input The input signal applied on this pin controls the N–Channel switching MOSFET in follower mode and therefore, linearly controls the RF output voltage. 10 Sense Input Pin It senses the negative voltage directly on the Power Amplifier. It is also the input pin of an internal Undervoltage Lockout circuit which blocks the switching of the N–Channel MOSFET if the sensed voltage is more positive than –3.0 V. 11 VBB Triple This is the positive pin of the output filter capacitor in the voltage tripler. The triple voltage at that pin is used internally to supply the inverting charge pump and the gate amplifier. 12 VBB Double This is the positive pin of the output filter capacitor in the voltage doubler. 13 Idle Mode Input This pin is used to set the circuit in Low Power Consumption Standby mode. It is CMOS compatible, i.e. a voltage lower than 0.5 V applied on this pin makes the device go into Standby mode in which the current consumption is lower than 1.0 µA. The MC33169 is then awakened by a voltage higher than 2.0 V applied on that pin. 14 VCC This is the supply input pin for the MC33169, VCC voltage ranges from 2.7 V to 7.2 V. Figure 1.

Controlling the power drain of the RF Amplifier extends operating battery life in many portable systems. Outputs The IC is designed to provide a –4.0 V bias to the gate of the RF Ampllifier MESFET devices prior to application of a positive battery voltage to the drain. The negative output voltage can provide up to 5.0 mA of current. The positive voltage control requires an external N–Channel logic level MOSFET, connected as a source follower. The Gate Drive Output, Pin 8, can source or sink 3.0 mA to the external MOSFET. The low drive current slows the MOSFET 6 switching speed, thereby minimizing voltage glitches on the VCC line which could cause disturbances to other circuitry. Inputs A Sense Input, Pin 10, protects the Power Amplifier load by monitoring the level of the negative output voltage. If the negative voltage magnitude falls below a preset level, 3.2 V typical, an undervoltage lockout circuit disables the external MOSFET gate drive. The Tx Power Control Input controls the N–Channel external switching MOSFET in source follower mode, which allows linear control of the RF Output voltage level. The Idle mode input is CMOS compatible, allowing the RF Amplifier to be placed in a standby mode, drawing less than 1.0 µA from the power source. MOTOROLA ANALOG IC DEVICE DATA MC33169 Figure 10.
