TERMINAL FUNCTIONS (continued)
TERMINAL
I/O
DESCRIPTION
NAME
NO.
DEFDCDC3
32
I
Input signal indicating VDCDC3 voltage.
TPS650240: 0 = 1.0V, 1 = 1.3V
TPS650241: 0 = 0.9V, 1 = 1.375V
TPS650242: 0 = 1.0V, 1 = 1.5V
TPS650243: 0 = 1.0V, 1 = 1.2V
TPS650244: 0 = 1.55V, 1 = 1.6V
TPS650245: 0 = 0.9V, 1 = 1.1V
EN_DCDC1
20
I
VDCDC1 enable pin. A logic high enables the regulator, a logic low disables the regulator.
EN_DCDC2
19
I
VDCDC2 enable pin. A logic high enables the regulator, a logic low disables the regulator.
EN_DCDC3
18
I
VDCDC3 enable pin. A logic high enables the regulator, a logic low disables the regulator.
LDO REGULATOR SECTION
VINLDO
15
I
Input voltage for LDO1 and LDO2
VLDO1
16
O
Output voltage of LDO1
VLDO2
14
O
Output voltage of LDO2
EN_LDO
17
I
Enable input for LDO1 and LDO2. Logic high enables the LDOs, logic low disables the LDOs
EN_Vdd_alive
24
I
Enable input for Vdd_alive LDO. Logic high enables the LDO, logic low disables the LDO
Vdd_alive
12
O
Output voltage for Vdd_alive
FB_LDO1
11
I
Feedback pin for LDO1
FB_LDO2
10
I
Feedback pin for LDO2
CONTROL AND I2C SECTION
MODE
23
I
Select between Power Safe Mode and forced PWM Mode for DCDC1, DCDC2 and DCDC3. In Power Safe
Mode PFM is used at light loads, PWM for higher loads. If PIN is set to high level, forced PWM Mode is
selected. If Pin has low level, then Device operates in Power Safe Mode.
PWRFAIL
21
O
Open drain output. Active low when PWRFAIL comparator indicates low VBAT condition.
PWRFAIL_SNS
30
I
Input for the comparator driving the /PWRFAIL output
10
