MAX15162ATG Evaluation Kit Evaluates: MAX15162ATG+/ MAX15162AATG+ General Description Features The MAX15162ATG evaluation kit (EV kit) is a fully 8V to 60V Wide Input Voltage Range assembled and tested surface-mount circuit board that Integrated Dual-Power MOSFET with Turn-on contains all components necessary to evaluate the Resistance 200m MAX15162ATG+/MAX15162AATG+ dual-channel circuit Dual-Channel Independent or Parallel Mode breaker IC for power amplifier system. The IC is in compact Configuration 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 Undervoltage Lockout independent single-channels or one parallel dual-channel Enable Input for Individual Channel circuit breaker. The EV kit provides multilevel overcurrent- Constant Power Control at Startup limit protection and pin-strap programmable current-limit Startup Watchdog Timer level up to 1.5A for each channel. Startup IN-to-OUT Short Protection The EV kit demonstrates the full functionality of the MAX15162ATG+/MAX15162AATG+, such as IN-OUT Over-current and Overtemperature Fault Status short protection during startup, inrush current control, Indication on Individual Channel input undervoltage-lockout (UVLO), programmable 3% Accuracy Current Reporting on Individual Channel overcurrent shutdown delay time and fast large overcurrent Multi-Level Overcurrent Limit Protection protection. The EV kit also features current monitoring/ reporting with 3% accuracy (0.8~1.5A) on individual Programmable Current Limit Level channel and overcurrent/overtemperature fault status Programmable Overcurrent Shutdown Delay Time indication. Latch in a Fault Event (MAX15162ATG+) Warning: The EV kit is designed to operate with high voltages. Dangerous voltages are present on this EV kit and on equipment Auto-Retry in a Fault Event with Programmable Auto- connected to it. Users who power up this EV kit or power the Retry Time (MAX15162AATG+) sources connected to it must be careful to follow safety procedures Built-In Thermal Shutdown Protection appropriately to work with high-voltage electrical equipment. Under severe fault or failure conditions, this EV kit may dissipate Proven PCB Layout large amounts of power, which could result in the mechanical Fully Assembled and Tested ejection of a component or of component debris at high velocity. Operate this kit with care to avoid possible personal injury.

The EV kit features components and circuits that demonstrate the full functionality of the Procedure MAX15162ATG+/MAX15162AATG+ in both independent The EV kit is fully assembled and tested. Follow the steps mode and parallel mode. 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 1) Configure IMONx and ENx pins with power supply process and determines the operation mode. To configure off (x = 1, 2): the device in independent mode on the EV kit, leave J9 a) Independent Mode: Leave jumper J9 open (to open and connect J11 to any resistor from R16 to R19 disconnect IMON1 and IMON2), install a shunt and connect J12 to any resistor from R20 to R23. To across any one of four pin-straps of J11 and J12 configure the device in parallel mode, install a shunt at J9 individually (configure OC limit of channel 1 and to tie IMONx together besides configuring J11 and J12. channel 2 individually). Leave jumper J8 open In addition, J8 must also be shunted to tie EN1 and EN2 (to disconnect EN1 and EN2) and shunt pins 2-3 together. See Table 1 for operating mode settings. 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 The dual channels of the MAX15162ATG+/ tie IMON1 and IMON2 together), install a shunt MAX15162AATG+ can be individually enabled or disabled across any one of four pin-straps of J11 (J12) through the ENx (x=1, 2) by driving it above or below the and leave J12 (J11) open. Install a shunt at Enable threshold voltage. The EV kit allows ENx pins to jumper J8 (to tie EN1 and EN2 together) and be pulled up with VIN rising edge by shunting 1-2 pins shunt pins 2-3 of J4 or J6. Switch SW1 and SW2 of J4 and J6. ENx pins can also be pulled high by 3.3V to their pin-1. generated by external linear regulator MAX6765 by shunting 2) Connect electronic loads to the output: 2-3 pins of J4 and J6.
