TPS1035 POWER STAGE PIN DESCRIPTIONS

Pin

Function

Description

1

INPUT

Input pin for power stage.

2

VDD

Positive supply pin.

3

OUTPUT

Output pin.

4

PGND

Power Ground pin.

5

VBOOT

Bootstrapped voltage to supply drive to gate of high-side output MOSFET.

6

SLEEP

Sleep Input pin. When set to logic level high, sleep mode is enabled. When set

to logic level low (grounded), sleep mode is disabled.

7

BYPASS

Bypass pin for the gate drive power supply. The gate drive for the output mosfets

are internally generated from VDD. This pin should be connected to ground

through a 1.0uF or larger capacitor. This pin must be connected to the Fault pin

(pin 8) through a 27kΩ resistor.

8

FAULT

Fault Output pin. During normal operation this pin is high. If an overcurrent or

over temperature condition is detected the fault pin will become low. This pin

must be connected to the Bypass pin (pin 7) through a 27kΩ resistor.
