TPS2306 Dual Sequencing Hot Swap Power Manager
1
Introduction
This User’s Guide describes the use and operating features of the TPS2306 evaluation module (EVM). The
Texas Instruments (TI) TPS2306 is a dual channel hot-swap power manager with programmable output
sequencing control. It integrates inrush current control, electronic circuit breaker, power-up and power-down
sequencing and fault indication functions to provide plug-in module designers with a configurable hot swap
solution. The TPS2306 EVM is a PCB-based tool used to evaluate the performance of the device in simulated
live insertion and removal actions.

Description
The TPS2306 provides hot swap control, fault handling and sequencing of two positive voltage supplies. The
input supply operating range of 2.75 V to 13.6 V makes the TPS2306 applicable in numerous digital and
signaling applications.
The TPS2306 operates in conjunction with two external N-channel MOSFETs to limit inrush current, and control
output sequencing and slope during live insertion events, while creating a low impedance interface between
supply and load after insertion transients have passed. An on-chip linear current amplifier (LCA) provides
closed-loop control of the current sourced to the load circuitry during hot swap. An internal charge pump boosts
the Channel 1 input supply to fully enhance the MOSFETs under subsequent steady-state loading conditions.
A second level of power bus protection is provided by fast over-current comparators monitoring the load current
levels of each channel. In a short-circuit event, the overcurrent comparators will rapidly latch off both N-channel
MOSFETs.
A high degree of user programmability allows configuration of the TPS2306 over a wide range of load
characteristics. Control inputs allow the module designer to set the maximum current level and inrush current
profile (slew rate) during module start-up. Under fault conditions, an on-chip timer controls how long the HSPM
is allowed to operate in current-control mode prior to turning off the pass elements. Timer duration is easily
programmed with a single external capacitor.
Supply sequencing control is implemented via four comparator inputs to independently control the ramp-up and
ramp-down of each supply output. A TTL- and CMOS-compatible enable input allows system-level control of
the output status and selection of the low-power sleep mode. The open-drain FAULT output provides single line
fault reporting to the system host or controller.
