RHRPMICL1A Introduction This user manual provides an overview of the EVAL-RHRICL1ATV1, EVAL-RHRICL1ALV1 and EVAL-RHRICL1AFV1 evaluation boards developed for the RHRPMICL1A, rad-hard integrated current limiter IC. One evaluation board for each of the three operative modes of the RHRPMICL1A is available. Each evaluation tool includes all external components, needed for a complete electrical evaluation of the device functionality in the selected configuration. -
Page 2: Description
UM2605 Description Description The RHRPMICL1A is an integrated current limiter designed to work as a high-side gate driver or intelligent power switch driver, with an external P-channel power MOSFET. It can be used as a universal solution to protect a power supply (from 8.5 V) from anomalous external current demand (for example, even in case of a short-circuit condition). -
Page 3: Common Features And Parameters
UM2605 Common features and parameters Common features and parameters This section describes the features that are in common to the three boards, such as: UVLO, floating ground configuration, current limitation, analog and digital telemetries, and explains how to customize them by changing the external components on the board. -
Page 4: Analog Telemetry
UM2605 Analog telemetry 1. Vcc <14.8 V The Zener diode chain is OFF and the R is used to protect the system against a potential internal failure of the device. Since the typical current consumption of the ICL device is ~ 1.5 mA (the current contribution of the V GND Zener diode chain is null in this case), in order to have a certain V , the R... -

UM2605 Operations Operations 4.2.1 Power on and testing environment Connect a 37 V power supply to CN1, the load on CN2. The telecommand section is available on the TC3 connector. Separated signals TC_ON and TC_OFF are applied to drive properly the telecommand interface. Connect a jumper on SW1 in the position 1-2 to set the latched-OFF configuration, or in the position 2-3 for latched-ON one. -
Page 14: Telecommand Interface
UM2605 Operations 4.2.3 Telecommand interface The telecommand interface is available through the TC_ON and TC_OFF pins of the ICL device. On the EVAL- RHRICL1ALV1 board the telecommand pins are driven by two additional MOSFET transistors (NCH_1 and NCH_2). The gates of these transistors are available by TC3 connector. The device is switched-ON by applying a positive pulse signal of the typical duration of 100 μs between terminal 3 and 2 of connector TC3 (Figure 12. -
