+## AXP853T Battery Support Summary
7
+
8
+The **AXP853T does not support battery charging.** Unlike the AXP2101, which is a battery-management PMIC, the AXP853T is a **system-rail PMIC** designed to provide high-current power distribution for multi-core processors.
9
+
10
+| Feature | AXP853T | AXP2101 |
11
+| :--------------------- | :----------------------- | :---------------------- |
12
+| **Integrated Charger** | **No** | Yes (1.5A Buck Charger) |
13
+| **Fuel Gauge** | **No** | Yes (E-Gauge™ 3.0) |
14
+| **Battery Pins** | No (System VIN only) | Yes (VBUS, BAT, TS) |
15
+| **Primary Focus** | Complex Power Sequencing | Battery Life & Charging |
16
+
17
+**Design Note:** If your project requires a battery, you must use a standalone charger IC (e.g., **TP4056** or **BQ24195**) to feed power into the AXP853T system input.
18
+

+
21
+## specs
22
+
23

+## Alternatives to AXP2101 PMIC
45
+
46
+Several Power Management ICs (PMICs) offer a similar "all-in-one" approach to the **AXP2101**, integrating multi-channel voltage regulation (DCDCs and LDOs) with battery charging and fuel gauging.
47
+
48
+### 1. Within the AXP Series (X-Powers)
49
+
50
+
51
+
52
+If you are already working within the AXP ecosystem (commonly used in ESP32-S3 and development boards), these are the closest siblings:
53
+
54
+* **AXP192**: The predecessor to the AXP2101. It is widely used in devices. While it has fewer channels, it is well-documented and has extensive community library support.
55
+* **AXP2102**: A variant often used in similar applications, sometimes with slight differences in the power-up sequence or specific LDO voltage ranges.
56
+* **AXP216**: Targeted at higher-power applications; it offers more current output on certain rails than the AXP2101.
57
+
58
+### 2. Industry Standard Alternatives
59
+
60
+- [[NPM1300-dat]]
61
+
62
+These chips are widely used across the industry for portable IoT, wearables, and multi-core SoC power management:
63
+
64
+| Chip | Key Strengths | Best Use Case |
65
+| :--- | :--- | :--- |
66
+| **Nordic nPM1300** | Ultra-high efficiency; very accurate fuel gauge; 2x Buck + 2x LDO. | **nRF52/nRF53** or ultra-low-power BLE projects. |
67
+| **Analog MAX77658** | Uses SIMO (Single-Inductor Multiple-Output) to save board space. | **Hearables** (earbuds) and tiny wearables. |
68
+| **Maxim MAX20360** | Integrated haptic driver and ultra-low quiescent current. | **Smartwatches** and medical sensors. |
69
+| **Active-Semi ACT81458** | High integration with 3 DCDCs and multiple LDOs. | Multi-core processors and **industrial IoT**. |
70
+
71
+
72
+
73
+### 3. Comparison: AXP2101 vs. nPM1300
74
+| Feature | AXP2101 | Nordic nPM1300 |
75
+| :--- | :--- | :--- |
76
+| **Charging Current** | Up to 1.5A | Up to 800mA |
77
+| **DCDC Channels** | 4 (up to 2A) | 2 (up to 200mA) |
78
+| **LDO Channels** | 11 | 2 (50mA/100mA) |
79
+| **Main Advantage** | High channel count for complex systems | USB-C compatibility & power efficiency |
80
+
81
+### Selection Advice
82
+* **Stick with AXP2101 if:** You need many power rails (e.g., for a camera, screen, and SD card on one board) or are working with ESP32-based hardware where libraries are already available.
83
+* **Switch to nPM1300 if:** You are prioritizing battery life above all else and only need a few power rails for a low-power microcontroller.
84
+* **Consider MAX77658 or ACT81458 if:** You need specialized features like haptic feedback or are designing for a more complex SoC environment that requires higher current on certain rails.
