UG167 Evaluation Board Rev.1.00 Jul 31, 2018 Overview The HIP2105-6MBEVAL1Z is an evaluation tool for the HIP2105 HIP2106A half bridge MOSFET drivers. This tool consists of a mother board and HIP2105DBEVAL1Z or HIP2106ADBEVAL1Z evaluation daughter cards. The mother board platform provides an on-board microcontroller that is used to generate appropriate control inputs to the HIP2105 or HIP2106A.

The HIP2105-6MBEVAL1Z is a fully self-contained test platform for evaluation of the HIP2105 or the HIP2106A, which are provided on daughter cards. The HIP2105-6MBEVAL1Z mother board and associated daughter cards are the same test boards used by the Renesas application engineers and IC designers to evaluate the performance of the HIP2105 and HIP2106A MOSFET drivers.
HIP2105-6MBEVAL1Z 2. Functional Description Half Bridge The bridge is composed of two (NVTFS5C466NLWF) 51A, 40V MOSFETs. Each FET has an optional gate-to- source and drain-to-gate capacitors to allow the emulation of FETs with larger capacitances if desired. An optional series gate resistor is also provided for each bridge FET that can also be used the emulate the internal gate resistance.

HIP2105-6MBEVAL1Z 2. Functional Description User Assembly Options The following optional assembly features are provided on the evaluation mother board: • Series connected diode (D1) on the VBAT input to the HIP2106A daughter card for holding up V when there is severe ripple voltage from a Li-ion battery.

HIP2105-6MBEVAL1Z 2. Functional Description The following user optional assembly features are provided on the HIP2105, HIP2106A daughter cards. • The HO = HGATE and LO = LGATE outputs have options for a bypass diode across a series connected gate resistor for slower turn-on and faster turn-off of the driven bridge FET. The default configuration includes the bypass diode in parallel with a 0Ω...

HIP2105-6MBEVAL1Z 2. Functional Description • The PHASE pin has an RC filter (R on the HIP2105 daughter card and R on the HIP2106A daughter card) This filter is used if needed. The default value for R is 0Ω and the capacitor between Phase and VSS is omitted.

HIP2105-6MBEVAL1Z 2. Functional Description with the internal inductance of the Li-ion battery (typically a few hundred nH). If the capacitor value is large enough, the battery voltage is close to the nominal unloaded value with minimal ripple. Another approach to reduce the amplitude of the voltage transient from the battery without increasing the size or value of the bridge capacitor, is to increase the PWM switching frequency.
