maxim integrated 2 component suppliers component list (continued) quick start required equipment max15096 ev kit 12v, 6a dc power supply voltmeter procedure the ev kit is fully assembled and tested. follow the steps below to verify board operation. caution: do not turn on the power supply until all connections are completed. 1) verify that a shunt is installed across pins 1-2 on jumper ju1. also ensure that jumpers ju2 and ju4 are opened and jumpers ju3 and ju5 are closed. 2) turn on the power supply and set the supply to 12v, then disable the power supply. 3) connect the positive terminal of the power supply to the in banana jack on the ev kit. connect the negative terminal of the power supply to the gnd banana jack. 4) enable the power supply. 5) verify that the voltage between the out and gnd banana jacks is 12v. 6) verify that the internal regulator voltage (reg) is 3.3v. 7) the ev kit is now ready for additional evaluation. detailed description of hardware the max15096 ev kit provides a proven design to evaluate the max15096. the ev kit can be conveniently connected between the system power and the load using the banana jacks provided for the input and output. pcb pads are provided to monitor and control the device sig - nals. the ev kit operates between 2.7v and 18v up to 6a load current capability. evaluating the max15096 the ev kit can be used to evaluate the max15096, with the max15096gwe+ installed. the max15096a/ max15096d are pin-to-pin compatible with the max15096. refer to the device data sheet for details on the max15096a and max15096d. circuit breaker (cb) jumper ju1 sets the current limit for the internal circuit breaker (cb) of the device. the cb pin can be connected to a fixed resistor (r5) or a potentiometer (r11) to set the current limit. see table 1 for shunt positions. the circuit-breaker threshold can be set according to the following formula: icb = [(rcb/6510) - 0.34] where i cb is in a and r cb (the resistor between cb and ground) is in ?. note: indicate that you are using the max15096 when contacting these component suppliers. table 1. ju1 jumper selection (cb) *default position. designation qty description u1 1 6a hot-swap solution (16 wlp) maxim max15096gwe+ or maxim max15096agwe+ or maxim max15096dgwe+ designation qty description 5 shunts 1 pcb: max15096 evaluation kit supplier phone website fairchild semiconductor 888-522-5372 www.fairchildsemi.com murata electronics north america, inc. 770-436-1300 www.murata-northamerica.com stmicroelectronics 408-452-8585 www.us.st.com tdk corp. 847-803-6100 www.component.tdk.com shunt position cb pin connected to current limit 1-2* r5 12a 2-3 r11 adjustable max15096/a/d evaluation kits evaluate: max15096/max15096a/max15096d www.maximintegrated.com
maxim integrated 3 setting the output slew rate an external capacitor (c3) is connected from gate to gnd on the ic to reduce the output slew rate during startup. during startup, a 5.9a (typ) current is sourced to enhance the internal mosfet with 10v/ms (typ). c3 can be calculated according to the following formula: c3 = (i gate x ?t)/?v gate where i gate is 5.9a (typ), ?t is the desired slew rate, and ?v gate is the voltage at the gate of the internal mosfet at turn-on. enable/present-detect inputs the ev kit features jumpers ju2 and ju3 to enable/ disable the output. ju3 allows simulation of pc express card being plugged in. out is enabled when prsnt is pulled low and en is pulled high . if prsnt is high, out is not enabled, regardless of en logic state see table 2 for jumper positions. undervoltage/overvoltage lockout the ev kit provides an option to configure the under - voltage/overvoltage-lockout threshold using a resistive divider, r1 and r2 from in to ground with the center tap connected to uvov. the ev kits undervoltage-lockout threshold is set to 7.1v (typ) and the overvoltage-lockout threshold is set to 15.8v (typ). refer to the device data sheet for mor details. timer jumper ju5 connects timer to reg, which sets the total response time of the fast-trip comparator to less than 200ns (typ). for adjustable response time, open ju5 and close ju4. ju4 connects timer to a 500k potentiom - eter (r6).see table 3 for shunt positions. use the following formula to set the fast-trip comparators response time: t fcd = 0.2 + r6 x 22.9 x 10 -3 where t fcd is the fast-trip comparator response time in s and r6 is the total resistance from timer to ground in k set by the 500k potentiometer. refer to the device data sheet for more details. table 2. ju2 and ju3 jumpers selection table 3. ju4 and ju5 jumpers selection *default position. shunt position en/ prsnt connections ev kit operation not installed (ju2) en pulled to reg with a 100k? pullup out enabled with prsnt low installed (ju3) prsnt forced to gnd out enabled with en high shunt position timer connected to t fcd not installed (ju4) r6 adjustable installed (ju5) reg 200ns max15096/a/d evaluation kits evaluate: max15096/max15096a/max15096d www.maximintegrated.com
