Features
• Based on the IPS4260LM quad low-side switch, which features:
– Operating range 8 to 50 V
– High Speed operation (trise, tfall < 1us)
– Process side operating current: configurable from 350 mA (per channel)
up to 2 A (parallelized channels)
– Low-power dissipation (RON(TYP) = 260 mΩ)
– Configurable low dissipative cutoff function in overload conditions
– Per-channel overload, short circuit, and thermal junction protections
– Fast decay of inductive loads with integrated catch diodes
– Open load detection
– Undervoltage lock-out
– Loss of supply / loss of ground protection
– HTSSOP20 package
• Galvanic isolation between logic and process sides by STISO620, STISO621
digital isolators and isolated DC-DC converter
• Selectable supply of the IPS4260LM from on board isolated dc-dc converter
(SW7 close 1-2), or from 24 V supply rail (SW7 close 2-3)
• Process side operating range: 10 V (SW7 close 1-2) or 10 to 30 V (SW7 close
2-3)
• Process side supply rail reverse polarity protections (J1 open when SW7 =
close 2-3)
• Application board logic side operating voltage 3.3 (SW1 close 1-2) or 5 V (SW1
close 2-3)
• Green LEDs for outputs on/off status (J6 close 1-2, 3-4, 5-6, 7-8)
• Open load detection enable (J7 close 1-2, 3-4, 5-6, 7-8) / disable (J7 open)
• Red LEDs for overload/thermal warning (D8) and open load (D7) diagnostic
• Selectable current limitation level (J8 close 1-2 = 0.5A, or 3-4 = 1A, or 5-6 =
2A)
• Cutoff enable (J8 open 7-8) / disable (J8 close 7-8) options
• Per channel overload diagnostic available on CN5[9,10] and CN8[5, 6]
• Easy parallelization of input signals (J9) and output channels (J10)
• Compatible with STM32 Nucleo development boards
• Equipped with Arduino® UNO R3 connectors
• RoHS and China RoHS compliant
• CE certified
