3 Description
The TPD3S716-Q1 is a single-chip solution for short-
to-battery, short-circuit, and ESD protection with an
adjustable current-limit for the USB connector’s VBUS
and data lines in automotive applications. The
integrated data switches provide best-in-class
bandwidth for minimal signal degradation while
simultaneously providing 18 V short-to-battery
protection. The high bandwidth of 1 GHz allows for
USB2.0 high-speed data rates for applications like
Car Play. Extra margin in bandwidth above 720-MHz
also helps to maintain a clean USB 2.0 eye diagram
with the long captive cables that are common in the
automotive USB environment. The short-to-battery
protection isolates the internal system circuits from
any over-voltage conditions at the VBUS_CON, VD+,
and VD– pins. On these pins, the TPD3S716-Q1 can
handle over-voltage protection up to 18 V for hot plug
and DC events. The over-voltage protection circuit
provides the most reliable short-to-battery isolation in
the industry, shutting off the data switches in 200 ns
and protecting the upstream circuitry from harmful
voltage and current spikes.
The VBUS_CON pin also provides an adjustable current
limited load switch and handles short-to-ground
protection. The device supports VBUS currents up to
2.4 A, allowing support for charging USB BC1.2, USB
Type-C 5V/1.5A, and proprietary charging schemes
up to 2.4 A. The separate enable pins for data and
VBUS allow for both host and client-OTG mode.
TPD3S716-Q1 also integrates system level IEC
61000-4-2 and ISO 10605 ESD protection on its
VBUS_CON, VD+, and VD– pins removing the need to
provide external high voltage, low capacitance
diodes.
