The MAX15162ATG evaluation kit (EV kit) is a fully
assembled and tested surface-mount circuit board that
contains all components necessary to evaluate the
MAX15162ATG+/MAX15162AATG+ dual-channel circuit
breaker IC for power amplifier system. The IC is in compact
24-pin, 4mm x 4mm TQFN package. The EV kit is powered
from an 8V to 60V DC supply and can be configured as two
independent single-channels or one parallel dual-channel
circuit breaker. The EV kit provides multilevel overcurrent-
limit protection and pin-strap programmable current-limit
level up to 1.5A for each channel.

The EV kit demonstrates the full functionality of the
MAX15162ATG+/MAX15162AATG+, such as IN-OUT
short protection during startup, inrush current control,
input undervoltage-lockout (UVLO), programmable
overcurrent shutdown delay time and fast large overcurrent
protection. The EV kit also features current monitoring/
reporting with ±3% accuracy (0.8~1.5A) on individual
channel and overcurrent/overtemperature fault status
indication.

Warning: The EV kit is designed to operate with high voltages.
Dangerous voltages are present on this EV kit and on equipment
connected to it. Users who power up this EV kit or power the
sources connected to it must be careful to follow safety procedures
appropriately to work with high-voltage electrical equipment.
● Auto-Retry in a Fault Event with Programmable Auto-
Retry Time (MAX15162AATG+)
● Built-In Thermal Shutdown Protection
● Proven PCB Layout
Under severe fault or failure conditions, this EV kit may dissipate
large amounts of power, which could result in the mechanical
ejection of a component or of component debris at high velocity.
Operate this kit with care to avoid possible personal injury.

Quick Start
Detailed Description of Hardware
The MAX15162ATG EV kit is a fully assembled and tested
board to evaluate the performance of the MAX15162ATG+/
MAX15162AATG+ integrated dual-channel circuit breaker.

MAX15162ATG+/
MAX15162AATG+ is well suited for telecommunication
Power Amplifier systems. The EV kit features components
and circuits that demonstrate the full functionality of the
MAX15162ATG+/MAX15162AATG+ in both independent
mode and parallel mode.
● 100MHz dual-trace oscilloscope
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
Mode Configuration
Caution: Do not turn on the power supply until all
connections are completed.
The MAX15162ATG+/MAX15162AATG+ device detects
IMONx (x = 1, 2) pins connection during initialization
process and determines the operation mode. To configure
the device in independent mode on the EV kit, leave J9
open and connect J11 to any resistor from R16 to R19
and connect J12 to any resistor from R20 to R23. To
configure the device in parallel mode, install a shunt at J9
to tie IMONx together besides configuring J11 and J12.
In addition, J8 must also be shunted to tie EN1 and EN2
together. See Table 1 for operating mode settings.
1) Configure IMONx and ENx pins with power supply
off (x = 1, 2):
a) Independent Mode: Leave jumper J9 open (to
disconnect IMON1 and IMON2), install a shunt
across any one of four pin-straps of J11 and J12
individually (configure OC limit of channel 1 and
channel 2 individually). Leave jumper J8 open
(to disconnect EN1 and EN2) and shunt pins 2-3
of J4 and J6 respectively. Switch SW1 and SW2
to their pin-1.
Enable Input (ENx)
b) Parallel Mode: Install a shunt at jumper J9 (to
tie IMON1 and IMON2 together), install a shunt
across any one of four pin-straps of J11 (J12)
and leave J12 (J11) open. Install a shunt at
jumper J8 (to tie EN1 and EN2 together) and
shunt pins 2-3 of J4 or J6. Switch SW1 and SW2
to their pin-1.
The dual channels of the MAX15162ATG+/
MAX15162AATG+ can be individually enabled or disabled
through the ENx (x=1, 2) by driving it above or below the
Enable threshold voltage. The EV kit allows ENx pins to
be pulled up with VIN rising edge by shunting 1-2 pins
of J4 and J6. ENx pins can also be pulled high by 3.3V
generated by external linear regulator MAX6765 by shunting
2-3 pins of J4 and J6. See Table 2 for EN jumpers’ settings.
2) Connect electronic loads to the output:
a) Independent Mode: Connect two 1A electronic
loads to OUT1+/OUT1- and OUT2+/OUT2-
banana jack connectors individually. Disable the
load.
Current Limit Thresholds and
Current Monitor (IMONx)
The EV kit configures overcurrent limit threshold through
IMONx pins for each channel. Connect a resistor between
IMONx and GND to program the overcurrent limit threshold
in the device. In independent mode, connect J11 and J12
to the current-limit setting resistors individually. The
following equation is used to calculate current-limit setting
resistor:
b) Parallel Mode: Solder R33 (0Ω) to connect
OUT1+ and OUT2+. Connect one 2A electronic
load to OUT1+ and OUT1- banana jack connectors
and disable the load.
3) Connect the external DC power supply to VIN and
GND banana jack connectors. Turn on VIN at 0V and
ramp it up to 8V or higher.

Overcurrent Protection Delay (RDLY)
Fault Status Indication (ALRTx)
The EV kit configures the overcurrent protection response
delay time by connecting DLY pin and GND through a
resistor RDLY, as shown in Table 5. When the current
through the device reaches the overcurrent limit threshold,
the internal delay timer begins to count up. If the current
drops back below the overcurrent limit within the delay
The EV kit indicates fault status through red LED
connected ALRT pin in each channel. The LED turns on
when the following faults occur:
● MOSFET is not turned on.
● Input voltage drops to UVLO level.
● Overcurrent limit is triggered.
● Overtemperature level is reached.
● Startup watchdog times out.
● IMONx pin are open.
