DESCRIPTION

The TPS206xA power-distribution switches are intended for applications where heavy capacitive loads and

short-circuits are likely to be encountered. The TPS206xA family is pin-for-pin compatible with the TPS206x

family with a tighter overcurrent tolerance. This family of devices incorporates two 70-mΩ N-channel MOSFET

power switches for power-distribution systems that require multiple power switches in a single package. Each

switch is controlled by a logic enable input. Gate drive is provided by an internal charge pump designed to

control the power-switch rise and fall times to minimize current surges during switching. The charge pump

requires no external components and allows operation from supplies as low as 2.7 V.

Each device limits the output current to a safe level by switching into a constant-current mode when the output

load exceeds the current-limit threshold or a short is present. Individual channels indicate the presence of an

overcurrent condition by asserting its corresponding OCx output (active low). Thermal protection circuitry

disables the device during overcurrent or short-circuit events to prevent permanent damage. The device recovers

from thermal shutdown automatically once the device has cooled sufficiently. The device provides undervoltage

lockout to disable the device until the input voltage rises above 2.0 V. The TPS206xA is designed to current limit

at 1.6 A typically per channel.
