Inductive Heater Circuit Design
Thought for 54 sec
Confirmed. I’ll proceed with these exact parts and connections:
Parts to add
- ADR4525ARZ ×1
- 47Ω 0603 Resistor ×2
- 100nF0603 ×1
Wiring to apply
- IR2110 input conditioning:
- Reference and IA power:
- ADR4525ARZ VIN → VIN_12V, GND → NET_COM
- ADR4525ARZ VOUT → IC1 REF
- 100nF0603 from ADR4525 VOUT → NET_COM (place close to the ref)
- IC1 Vs+ → VIN_12V; Vs− → NET_COM
Notes
- Keep the two new 47 Ω resistors close to U1 HIN/LIN pins.
- Maintain Kelvin sense from R1 to IC1 IN+/IN− as previously defined.
- After placement, we should run the Review to check for missing connections and decoupling proximity.
Shall I also rename or confirm the net labels now?
- VIN_12V, NET_COM, HIN, LIN, VOUT_3V3, VDC+, VDC−, HB_OUT
Rename VIN_12V to VCC_12V and NET_COM to GND_REF.

Acknowledged. Please update net names as follows:
- Rename VIN_12V → VCC_12V
- Rename NET_COM → GND_REF
After renaming, verify these key connections still reference the renamed nets:
- U3 IN → VCC_12V; C5 P1 → VCC_12V
- U1 VCC → VCC_12V; C7 and its 100 nF decoupler between VCC and GND_REF
- IC1 Vs+ → VCC_12V; Vs− → GND_REF; REF from ADR4525 VOUT; ADR4525 VIN → VCC_12V; ADR4525 GND → GND_REF; 100 nF from ADR4525 VOUT → GND_REF
- R1 low-side shunt: pad A → VDC−, pad B → GND_REF; IC1 IN+ Kelvin to pad A, IN− Kelvin to pad B
- U2 GND → GND_REF; C6 2 → GND_REF; C6 1 and U3 OUT → VOUT_3V3
- HIN/LIN conditioning: pull-downs from U1 HIN and LIN to GND_REF; 47 Ω series from U2 IO25/IO26 to U1 HIN/LIN
Want me to run a review afterward to catch any dangling nets after the rename?
To get started, talk to Flux or create a New Document.
