3 Description

The TPS48130-Q1 is a 100V low IQ smart high

side driver with protection and diagnostics. With wide

operating voltage range of 3.5V–95V, the device is

designed for 12V, 24V, and 48V system designs.

The device can withstand and protect the loads from

negative supply voltages down to –65V.

TPS48130-Q1 has integrated two gate drives with

1.69A source and 2A sink capacity to drive MOSFETs

in the main path and 165μA source and 2A sink

capacity for the low power path.

In the low power mode with LPM = Low, the low

power path FET is kept ON and the main FETs

are turned OFF. The device consumes low IQ of

35μA (typ) in this mode. Auto load wakeup threshold

to enter into active state can be adjusted using

ISCP/LWU pin. IQ reduces to 1μA (typ) with EN/UVLO

low.

The device provides adjustable short circuit protection

using MOSFET VDS sensing or by using an external

RSNS resistor. Auto-retry and latch-off fault behavior

can be configured. The device also features diagnosis

of the internal short circuit comparator using external

control on SCP_TEST input.

The TPS48130-Q1 is available in a 19-pin VSSOP

package.
