PIN DESCRIPTION (L3000N)
PowerSO-20
N
°
Name
Description
3
TIP
A line termination output with current capability up to 100mA (Ia is the current sourced from
this pin).
4
MNT
Positive Supply Voltage Monitor.
5VB+
Positive Battery Supply Voltage.
6
BGND
Battery ground relative to the VB+ and the VB- supply voltages.
It is also the reference ground for TIP and RING signals.
7VDD
Positive Power Supply +5V.
8VIN
2 wire unbalanced voltage input.
9
VBIM
Output voltage without current capability, with the following functions:
- give an image of the total battery voltage scaled by 40 to the low voltage part.
- filter by an external capacitor the noise on VB+ and VB-.
1,10,11,20
VB-
Negative Battery Supply Voltage.
12
AGND
Analog Ground. All input signals and the VDD supply voltage must be referred to this pin.
13
REF
Voltage reference output with very low temperature coefficient. The connected resistor sets
Internal circuit bias current.
14
C1
Digital signal input (3 levels) that defines device status with pin 12. In thermal overload
condition a 240mA typical current is sunk by this pin.
15
C2
Digital signal input (3 levels) that defines device status with pin 11.
16
IT
High precision scaled transversal line current signal.
17
IL
Scaled longitudinal line current signal.
19
RING
B line termination output with current capability up to 100mA (Ib is the current sunk into this
pin).
2, 18
N.C.
Not connected.
Notes: 1) All information relative to the PowerSO-20 package option should be considered as advanced information on a new product now in
developement or undergoing evaluation. Details are subject to change without notice.
