MOTOROLA ANALOG IC DEVICE DATA
PIN FUNCTION DESCRIPTION
Pin
Name
Description
1
C2 Input
This is the positive pin for the charge pump capacitor in the voltage doubler.
2
C1/C2
This is the negative pin for the charge pump capacitors.
3
C1 Input
This is the positive pin for the charge pump capacitor in the voltage tripler.
4
VO Output
It delivers a regulated negative voltage of –4.0 V or –2.5 V depending on the product version. 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 (–4.0 V version) or –2.0 V (–2.5 V version).
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
Idle Mode Input
This is the positive pin of the output filter capacitor in the voltage doubler.
13
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
μ
A. 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.
