3 Description

The TPS48100-Q1 is a 100V low IQ smart high

side driver with protection and diagnostics. With wide

operating voltage range of 3.5V–80V, the device is

suitable for 12V, 24V, and 48V system designs. The

device can withstand and protect the loads from

negative supply voltages down to –65V.

It has two strong 2A (source and sink) gate

drivers with separate control inputs (INP1, INP2) to

drive back to back MOSFETs in common source

configuration. Strong GATE driving enables power

switching using parallel MOSFETs in high current

system designs.

The device provides adjustable short-circuit

protection. Auto-retry and latch-off fault behavior can

be configured. Current sensing can be done either

by an external sense resistor or by MOSFET VDS

sensing. High side or low side current sense resistor

configuration is possible by using CS_SEL pin input.

The device also features diagnosis of the internal

short circuit comparator using external control on

SCP_TEST input.

A low quiescent current (35μA, typical) in operation

enables always ON system designs. Quiescent

current reduces to 1.5μA (typical) with EN/UVLO low.

The TPS48100-Q1 is available in a 19-pin VSSOP

package.
